UCC27223 - High-Efficiency predictive synchronous buck driver

Datasheet Summary

Description

The UCC27223 is a high-speed synchronous buck drivers for today’s high-efficiency, lower-output voltage designs.

Using Predictive Gate Drivet (PGD) control technology, these drivers reduce diode conduction and reverse recovery losses in the synchronous rectifier MOSFET(s).

Features

  • D Maximizes Efficiency by Minimizing Body-Diode Conduction and Reverse Recovery Losses D Transparent Synchronous Buck Gate Drive Operation From the Single Ended PWM Input Signal D 12-V or 5-V Input Operation D 3.3-V Input Operation With Availability of 12-V Bus Bias D High-Side and Low-Side ±3-A Dual Drivers D On-Board 6.5-V Gate Drive Regulator D ±3-A TrueDrive Gate Drives for High Current Delivery at MOSFET Miller Thresholds D Automatically Adjusts for Changing Operating Conditions D Thermall.
