Description: The ISL78223 is a high performance Zero Voltage Switching (ZVS) full-bridge PWM controller. 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 ISL78223’s feature set are average current monitoring and soft-start. The average current signal can be used for average current limiting, current sharing circuits, and average current mode control. Additionally, the ISL78
