UCC27221 Datasheet (Texas Instruments) - High-Efficiency Predictive Synchronous Buck Driver

UCC27221, High-Efficiency Predictive Synchronous Buck Driver

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).
