HIGH-EFFICIENCY PREDICTIVE SYNCHRONOUS BUCK DRIVER WITH ENABLE
Share:
Manufacturer

Description

DESCRIPTION
The UCC27223 is a high-speed synchronous buck drivers for today’s high-efficiency, lower-output voltage designs. Using Predictive Gate Drive™ (PGD) control technology, these drivers reduce diode conduction and reverse recovery losses in the synchronous rectifier MOSFET(s).
The UCC27223 includes an enable pin that controls the operation of both outputs. A logic latch is also included to keep both outputs low until the first PWM input pulse comes in. The RDS(on) of the SR pull-down sourcing device is also minimized for higher frequency operations.

FEATURES
• Maximizes Efficiency by Minimizing Body-Diode Conduction and Reverse Recovery Losses
• Transparent Synchronous Buck Gate Drive Operation From the Single Ended PWM Input Signal
• 12-V or 5-V Input Operation
• 3.3-V Input Operation With Availability of 12-V Bus Bias
• High-Side and Low-Side ±3-A Dual Drivers
• On-Board 6.5-V Gate Drive Regulator
• ±3-A TrueDrive Gate Drives for High Current Delivery at MOSFET Miller Thresholds
• Automatically Adjusts for Changing Operating Conditions
• Thermally Enhanced 14-Pin PowerPAD™ HTSSOP Package Minimizes Board Area and Junction Temperature Rise

APPLICATIONS
• Multiphase Converters in Combination With the TPS40090
• Non-Isolated 3.3-V, 5-V and 12-V Input dc-to-dc Converters for Processor Power, General Computer, Telecom and Datacom Applications
