UCC27222 - High-Efficiency Predictive Synchronous Buck Driver

Download the UCC27222 datasheet PDF. This datasheet also covers the UCC27221 variant, as both devices belong to the same high-efficiency predictive synchronous buck driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The UCC27221 and UCC27222 are 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).
