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.
Family Values
- Unique PWM ZVS control algorithm
- Easy for true peak mode control
- Easy for diode emulation and light load burst mode operation
- Easy For SR control
- Unique output current sense feature
- Simple implementation for brick wall constant current limit
- Simple implementation for current sharing control
Applications
- ZVS full bridge converters
- Telecom and datacom power
- Wireless basestation power
- File server power
- Industrial power systems
