ZVS Full-Bridge PWM Controller with Adjustable Synchronous Rectifier Control
FN6754 Rev 2.00 June 2, 2016
The ISL6754 is a high performance extension of the Intersil family of Zero-
Voltage Switching (ZVS) full-bridge PWM controllers. Like the ISL6752, 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.
Adding to the ISL6752’s feature set are average current monitoring and soft-start. The average current signal may be used for average current limiting, current sharing circuits and average current mode control. Additionally, the ISL6754 supports both
voltage- and current-mode control.
The ISL6754 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.
