ON Semiconductor – USB Power Delivery buck/boost controller


The NCP81239 USB Power Delivery (PD) controller from ON Semiconductor is a synchronous buck-boost controller which can convert an input ranging from 4.5V to 28V to an output compliant with the requirements of the USB Type-C PD 3.0 specification. It supports PD outputs up to 100W, and is compatible with the Qualcomm Quick ChargeTM technology.

The NCP81231 is a version of the NCP18239 providing step-down conversion only, providing a lower-cost option for designs which do not require boost conversion.

• I2C interface
• Switching-frequency range: 150kHz to 1.2MHz
• Meets timing requirements for slew-rate control during transition
• Over-voltage and over-current protection
