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.
New compact, low-noise LDO regulators from Toshiba
Toshiba has introduced the TCR5FM series of 35 LDO regulators, which help stabilise the DC power line for small devices, such as smartphones and wearables. The LDO regulators help address the challenge engineers face when designing battery-powered devices to switch from low-power mode to high-speed processing, thereby maximising performance and battery life. This mode switching can inherently destabilise the DC power line, requiring LDO regulators with fast load transient response.
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.
