USB Power Delivery

4-Switch Buck Boost

Controller

The NCP81239 USB Power Delivery (PD) Controller is a

synchronous buck boost that is optimized for converting battery

voltage or adaptor voltage into power supply rails required in

notebook, tablet, and desktop systems, as well as many other

consumer devices using USB PD standard and C−Type cables. 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.
