Buck Controller, USB Power Delivery and Type-C Applications

Overview

TopologyBuck Converter
IC revision2

Description

The NCP81231 USB Power Delivery (PD) Controller is a synchronous step down controller optimized for USB-PD type C solutions. They are ideal for docking station, car chargers, desktop, and monitor applications. The NCP81231 utilizes an I2C interface that can interface to a uC to meet USB-PD timing, slew rate, and voltage requirements. The NCP81231 operates from 4.5V to 28V.

Features

  • I2C configurability
  • Synchronous step down controller with drivers
  • Meets USB-PD specification
  • Overvoltage and overcurrent protection

Typical applications

  • Consumer
  • Networking Accessories
  • USB Type C
