Diodes APK43070Q enables 140 W USB-C charging

Diodes Incorporated has introduced the APK43070Q, an automotive-compliant synchronous buck controller combined with a USB Type-C® PD3.1 source controller for in-vehicle charging modules. Operating from a 4 V to 36 V input, it supports USB PD3.1 EPR and AVS up to 28 V plus SPR and PPS up to 21 V, enabling USB Type-C ports that deliver up to 140 W while reducing external component count and BOM cost. The device is designed for single-port and multi-port automotive USB Type-C charging systems, using external N-channel MOSFETs to let designers optimize efficiency and thermal performance. It also integrates I2C-based power sharing for up to eight ports without an external MCU and includes overvoltage, overcurrent, undervoltage and overtemperature protection plus connector moisture detection.
