LTC3722EGN-1#PBF

LTC3722-1 is a phase-shift PWM controller provide all of the control and protection functions necessary to implement a high efficiency, zero voltage switched (ZVS), full bridge power converter. Adaptive ZVS circuitry delays the turn-on signals for each MOSFET independent of internal and external component tolerances. Manual delay set mode enables secondary side control operation or direct control of switch turn-on delays. This device feature adjustable synchronous rectifier timing for optimal efficiency. A UVLO program input provides accurate system turn-on and turn-off voltages. It is widely used in application such telecommunications, infrastructure power systems, distributed power architectures, server power supplies etc.
