Revolutionary Compact MOSFET Initiative by ROHM Semiconductor
Introducing ROHM's Innovative AW2K21 MOSFET
ROHM Semiconductor has recently unveiled the AW2K21, a cutting-edge 30V N-channel MOSFET designed specifically for fast charging applications. This MOSFET showcases an impressive industry-leading ON-resistance of only 2.0m? in a remarkably compact 2.0mm x 2.0mm package, making it ideal for modern devices.
The Demand for Efficient Fast Charging Solutions
As the demand for compact devices with large-capacity batteries continues to grow, so does the need for rapid charging capabilities. The AW2K21 meets the stringent requirements set by smartphone manufacturers, such as operating at a maximum current rating of 20A and supporting breakdown voltages between 28V to 30V with minimal ON-resistance.
Traditionally, achieving these specifications required the use of two larger MOSFETs, complicating both installation and increasing component size on boards. However, ROHM's innovative design allows for a significant reduction in both the footprint and complexity, aligning perfectly with the needs of modern technology.
Enhancing Performance Through Innovative Structure
To achieve such high performance, ROHM has developed a proprietary structure that elevates cell density and reduces ON-resistance per chip area. The unique design integrates two MOSFETs into a single compact unit, allowing for bidirectional protection capability that is essential for many charging and power supply circuits.
Furthermore, by placing the drain terminal on the top surface, rather than the standard backside location, the AW2K21 is able to utilize a WLCSP (Wafer Level Chip Scale Package). This design enhances the chip-to-package area ratio, helping to lower ON-resistance even further. The result is a product that minimizes power loss while maintaining high current operation, which is crucial for fast-charging applications.
Significant Space and Power Savings
When compared to conventional solutions requiring two 3.3mm x 3.3mm MOSFETs, the AW2K21 only requires a single 2.0mm x 2.0mm chip to deliver equivalent performance. This represents an approximately 81% reduction in footprint and a 33% decrease in ON-resistance. In fact, when compared to GaN HEMTs, the AW2K21's ON-resistance is reduced by up to 50%, leading to notable improvements in power efficiency and space conservation in various applications.
Versatile Applications for Modern Electronics
The AW2K21 does not only excel in fast charging applications but is also versatile enough to serve as a unidirectional protection MOSFET in load switch scenarios. Its design maintains the lowest ON-resistance in the industry, showcasing ROHM's commitment to high performance and efficiency in smaller packages.
As ROHM Semiconductor strives toward further miniaturization, plans for an even more compact 1.2mm x 1.2mm model are also underway. This pushes the boundaries of what is currently available, ensuring that ROHM remains at the forefront of semiconductor technology.
Commitment to Sustainable Innovation
ROHM Semiconductor stands firm in its dedication to supporting the miniaturization and energy efficiency of electronic systems by providing compact, high-performance solutions. As technology evolves, ROHM aims to contribute positively towards creating a more sustainable society through innovative semiconductor designs.
