ROHM Develops a New Compact Thermal Printhead for A4-Sized Mobile Printers

　　ROHM has developed a new thermal printhead - KA2008-B07N70A - compatible with a 2-cell Li-ion battery (7.2V). Designed to deliver high print quality with low power consumption and optimized for A4 size printers (210mm width). Height has been reduced by approximately 16% from the conventional 14mm to a best-in-class* 11.67mm – contributing to a more compact printer design. Moreover, optimizing the heating element structure while improving the driver IC and wiring layout enables the support for 7.2V operation – reducing the applied energy required for printing by approximately 66% compared to conventional 12V drive (at 50 mm/s print speed). Adjustments to the individual wiring of the resistive elements ensure uniform heat generation, stabilizing print quality and enabling sharp and high-resolution 203dpi printing – even at speeds up to 100 mm/s.　　In recent years, the thermal printer market has been expanding in response to increasing demand to print qualified invoices and customs labels fueled by the growth of overseas e-commerce, as well as prescriptions and drug information sheets in hospitals and pharmacies. The demand for mobile printers has surged, particularly in the logistics and business sectors, where portability and ease of maintenance are highly valued. Among these trends, the adoption of A4-sized thermal printers has been growing in Asian markets, particularly in China – driving the need for 8-inch thermal printheads.　　A4-sized mobile printers face challenges such as high power consumption due to their wider print width, requiring larger battery capacities compared to smaller printers such as receipt printers. Moreover, the need for multiple driver ICs to control the heating elements in A4-sized printers often results in variations in heat generation due to the differences in wiring lengths between elements, which affect print quality, such as color development and uniformity.　　The KA2008-B07N70A addresses these challenges through an optimized design that enhances mechanical strength and durability by mitigating the effects of expansion and contraction caused by temperature changes. This meets the stringent durability requirements of A4-sized printers (the primary target market) while supporting both thermal and transfer printing methods – offering versatile printing for a wide range of applications.　　While thermal printheads are typically used in combination with connectors and a heat sink, the KA2008-B07N70A can also be supplied as a standalone board, providing greater design flexibility for printer manufacturers. For inquiries regarding the product as part of a set, please contact AMEYA360 or visit the contact page on ROHM’s website.　　Going forward, ROHM plans to develop a 300dpi resolution thermal printhead for mobile A4-sized printers by spring 2025. The company also intends to expand its considerable lineup with products that deliver high-speed printing with superior efficiency.　　Key Specifications　　For more information on printheads for mobile printers, please refer to the following URL on ROHM’s website: https://www.rohm.com/products/printheads/mobile-printers　　Sales Information Pricing: $14.50/unit (excluding tax)　　Availability: Now (OEM quantities)　　Application Examples • A4-sized mobile printers　　• Industrial control label printers　　• Tattoo stencil printers, etc.　　Terminology dpi (dots per inch)　　A unit of print resolution and density, indicating the number of dots that can be placed within a one-inch length (2.54 cm).　　Thermal Printing Method　　A printing technique in which heat is directly applied to thermal paper, causing a reaction that produces color.

ROHM’s Compact SOT-223-3 600V MOSFETs Contribute to Smaller, Lower Profile Designs for Lighting Power Supplies, Pumps, and Motors

　　ROHM has added a lineup of compact 600V Super Junction MOSFETs - the R6004END4 / R6003KND4 / R6006KND4 / R6002JND4 / R6003JND4. These devices are ideal for small lighting power supplies, pumps, and motors.　　In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated - spurring the demand for compact MOSFETs that are essential for switching operation.　　Generally, however, it has been difficult to reduce the size of Super Junction MOSFETs while maintaining an optimal balance between high breakdown voltage and low ON resistance. In response, after reviewing the shape of the mounted chip, ROHM was able to develop 5 models in the SOT-223-3 package (6.50mm × 7.00mm × 1.66mm) - providing a smaller, lower profile form factor without compromising the performance of conventional products.　　Compared to the conventional TO-252 package (6.60mm × 10.00mm × 2.30mm), ROHM’s new products reduce area and thickness by 31% and 27% - contributing to smaller, lower profile applications. At the same time, the same land pattern (footprint) as the TO-252 package can be used, enabling mounting on existing circuit boards without modification.　　Offering distinctive features, three of the models optimized for compact power supplies. The R6004END4, characterized by low noise, is suitable for applications where noise is a concern, while the R6003KND4 and R6006KND4, capable of high-speed switching, are ideal for sets requiring low loss, high efficiency operation. The R6002JND4 and R6003JND4 utilize proprietary PrestoMOS technology to achieve significantly lower switching losses by speeding up reverse recovery time (trr), making them well-suited for motors-equipped devices.　　Supporting materials such as application notes, technical documents, and SPICE simulation models for each product are available on ROHM’s website free of charge to enable quick market introduction.　　Going forward, ROHM will continue to expand its Super Junction MOSFET lineup in different packages and even lower ON resistances that contribute to solving social issues such as environmental protection by reducing power consumption in variety devices.　　Product Lineup　　For compact power supplies　　Application Examples • R6004END4 / R6003KND4 / R6006KND4: Lighting, Air conditioners, Refrigerators, etc.　　• R6002JND4 / R6003JND4: Motors for pumps, fans, copiers, etc.　　Online Sales InformationSales Launch Date: December 2023　　Pricing: $3.0/unit (samples, excluding tax)　　Online Distributors: DigiKey, Mouser, and Farnell　　The products will be offered at other online distributors as they become available.　　Online Distributors　　For More Information about ROHM’s Super Junction MOSFETVarious resources are available on ROHM's website, including application notes on the SOT-223-3 package and other documents essential for circuit design.　　https://www.rohm.com/support/super-junction-mosfet　　PrestoMOS“Presto” is an Italian musical term meaning “very fast.”　　PrestoMOS is ROHM’s original power MOSFET that maintains the high withstand voltage and low ON resistance of Super Junction MOSFETs while speeding up the reverse recovery time of the built-in diode. Reducing switching losses makes it ideal for a wider range of applications with inverter circuits, such as air conditioners and refrigerators.　　TerminologySuper Junction MOSFET (Metal Oxide Semiconductor Field Effect Transistor)　　A type of transistor, MOSFETs can be divided by device structure into DMOSFET (Double-diffused MOSFET), planar, and super junction topologies. Super Junction MOSFETs deliver superior breakdown voltage and output current than both DMOSFETs and planar types, featuring lower loss when handling large power.　　trr (Reverse Recovery Time)　　The time it takes for the built-in diode to switch from the ON state to completely OFF. The lower this value is, the smaller the loss during switching.

Ameya360:Micron Pushes DRAM Node for Mobile First

　　Micron Technology has been setting the pace for DRAM advancement of late. Its 1-beta DRAM technology continues the trend, but other major vendors are keeping up, even as it looks like DRAM prices will be lower in 2023.　　The company said at the beginning of November that it was shipping qualification samples of its 1-beta DRAM to select smartphone customers and that it’s ready for mass production. The advanced DRAM technology node, which will be used first on Micron’s low-power double data rate 5X (LPDDR5X) mobile memory that delivers speeds of 8.5 Gb/s, follows the company’s 1-alpha DRAM that began volume shipment in 2021.　　Micron’s 1-Beta LPDDR5X provides 16Gb per die capacity, 35% higher than the prior generation, and a 15% power saving compared to prior generation products. Thy Tran, Micron’s VP of DRAM process integration, said the new node is the result of new processes, materials, and equipment to advance Micron’s memory cell integration so it can shrink the memory cell array, including the application of its second-generation high-K metal gate (HKMG) technology. “We can then aggressively scale both the memory cell array in terms of size and also the rest of the circuitry in the dye to save space.”　　Aside from the performance improvements that will benefit smartphone functions such as camera launch, night mode and portrait mode and shake-free, high-resolution 8K video recording and in-phone video editing, Micron’s LPDDR5 based on its 1-beta DRAM boasts additional energy efficiency by implementing JEDEC’s new enhanced dynamic voltage and frequency scaling extensions core (eDVFSC) techniques. Adding eDVFSC at a doubled frequency tier of up to 3,200 megabits per second provides improved power savings controls to enable more efficient use of power based on end-user patterns.　　These features not only represent a faster smartphone camera but also demonstrate how artificial intelligence and machine learning are transforming smartphones into mobile editing studios, Tran said. “Be it photos, videos, or voice processing, memory is at the heart of everything we do.”　　Jim Handy, principal analyst with Objective Analysis, said what’s notable about Micron’s 1-beta is that it demonstrates Micron is strongly oriented toward pushing the technology forward with its HKMG technology to make DRAM as fast as it needs to go. “That makes for a complicated process.” If Micron were just trying to get the bits as cheap as they could be, it wouldn’t touch HKMG, he said.　　So far, DDR5 DRAM has mostly found its way into PCs, said Handy, and less so data centers. But Micron would like to see that change sooner than later so it can sell DDR5 before prices collapse, especially given the fact it’s been eight years since DDR4 was introduced. He noted that the company’s focus of late has been being more profitable rather than dominating market share.　　Although LPDDR5 will be the first to benefit from the 1-beta DRAM technology, Micron will expand the product portfolio that will be manufactured on this node as 2023 progresses for all segments of the memory market including High Bandwidth Memory (HBM).　　Not to be outdone, Samsung Electronics closed out 2022 by announcing the development of its 16-Gb DDR5 DRAM built using what it said is the industry’s first 12-nm-class process technology. Like Micron, Samsung is matching performance gains with power efficiency – its new DRAM consumes up to 23% less power than its predecessor. Mass production is set to begin in 2023.
