NCP81239 Datasheet, PDF (1/19 Pages) ON Semiconductor – USB Power Delivery 4-Switch Buck Boost Controller

NCP81239
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.
