ISL6752 Datasheet (Renesas) - ZVS Full-Bridge Current-Mode PWM

ISL6752, ZVS Full-Bridge Current-Mode PWM

DATASHEET ISL6752 ZVS Full-Bridge Current-Mode PWM with Adjustable Synchronous Rectifier Control FN9181 Rev 4.00 August 1, 2016 The ISL6752 is a high-performance, low-pin count alternative Zero-Voltage Switching (ZVS) full-bridge PWM controller.

Like Intersil’s ISL6551, it achieves ZVS operation by driving the upper bridge FETs at a fixed 50% duty cycle while the lower bridge FETs are trailing-edge modulated with adjustable resonant switching delays.

Compared to the more familiar phase-shifte

ISL6752 Features

* complemented PWM outputs for Synchronous Rectifier (SR) control. The complemented outputs may be dynamically advanced or delayed relative to the PWM outputs using an external control voltage. This advanced BiCMOS design features precision dead time and resonant delay control and an oscillator adjust
