About Intersil ZVS Full Bridge Controllers

The ISL675X family of controllers consists of high-performance, low-pin-count alternative zero-voltage switching (ZVS) full bridge pulse width modulating (PWM) controllers. These parts achieve 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.
