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). The UCC27221 has an inverted PWM input while the UCC27222 has a non-invert.
APPLICATIONS 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 On-Board 6.5-V Gate Drive Regulator D ±3.3-A TrueDrive Gate Drives for High Current Delivery at MOSFET Miller Thresholds D Automatically Adjusts for Changing Operating Conditions D Thermally Enhanced 14-Pin PowerPAD HTSSOP Package Minimizes Board Area and Junction Temperature Rise FUNCTIONAL APPLICATION DIAGRAM .
