UCD7138DRST General Description

The UCD7138DRST is a cutting-edge MOSFET driver designed to enhance the performance of digital PWM controllers in high-power isolated converter applications. With its 4-A and 6-A peak-current drive capability, this device offers asymmetrical rail-to-rail operation for optimal efficiency. The inclusion of a body-diode conduction-sensing circuit and turn-on delay optimization feature allows for precise control of synchronous-rectification (SR) dead-time, ultimately improving overall system efficiency

Key Features

Rapid Current Response
Simplified Control Logic
Fault Tolerant Operation
