ON Semiconductor - NCP81239
4-Switch Buck Boost Controller for USB Power Delivery and Type-C Applications




Consumer, Computing, All in Ones, USB Type-C & USB PD


The NCP81239 USB Power Delivery (PD) Controller is a synchronous buck boost that is optimized for converting battery voltage or adapter voltage into power supply rails required in notebook, tablet, and desktop systems, as well as many other consumer devices using USB PD standard and Type-C interface.

The NCP81239 USB Power Delivery (PD) Controller is a synchronous buck boost that is optimized for converting battery voltage or adapter voltage into power supply rails required in notebook, tablet, and desktop systems, as well as many other consumer devices using USB PD standard and Type-C interface. The NCP81239 is fully compliant to the USB Power Delivery Specification when used in conjunction with a USB PD or C−Type Interface Controller. NCP81239 is designed for applications requiring dynamically controlled slew rate limited output voltage that require either voltage higher or lower than the input voltage. The NCP81239 drives 4 NMOSFET switches, allowing it to buck or boost and support the consumer and provider role swap function specified in the USB Power Delivery Specification which is suitable for all USB PD applications. The USB PD Buck Boost Controller operates with a supply and load range of 4.5 V to 28 V.
