onsemi NCP81239MNTXG Power Switch IC 32-Pin, QFN

The ON Semiconductor NCP81239 USB Power Delivery (PD) Controller is a synchronous buck boost controller designed for USB PD and USB Type-C applications. The device is optimised for converting battery and adapter voltages in applications using USB PD standard and USB Type C connectors. When used in conjunction with a USB PD or USB Type-C controller the NCP81239 provides a fully compliant USB PD specification solution.

The NCP81239 provides dynamic slew rate control during voltage transition and accommodates the consumer/provider role swap as required in the USB PD specification. The USB PD Buck Boost Controller operates with a supply and load range of 4.5 V to 28 V.
