Infineon expands CoolGaN family to deliver up to 82 percent footprint reduction
Infineon has expanded its CoolGaN BDS 40 V G3 bidirectional switch (BDS) family with two new devices, the IGK048B041S and IGK120B041S. The new additions reduce PCB footprint by up to 82 percent and cut component count in half. For engineers designing within the strict spatial constraints of modern smartphones, notebooks, and wearables, this is a significant and quantifiable step forward. Targeting compact consumer devices, the new devices give power system designers greater flexibility to optimise efficiency and streamline designs without sacrificing performance.
ST’ hybrid controller simplifies full-feature implementation of USB-C sink premium applications
STMicroelectronics’ STUSB4531 USB Power Delivery (PD) sink controller introduces a new, patented hybrid mode that simplifies implementing optional USB PD features for added value in USB-powered and USB-chargeable devices.
ROHM develops an ultra-compact MOSFET ideal for fast charging
ROHM has developed a 30V N-channel MOSFET — AW2K21 — in a common-source configuration that achieves an industry-leading ON-resistance of 2.0mΩ (typ.) in a compact 2.0mm × 2.0mm package.
