General Description

The LTC®3722-1/LTC3722-2 phase-shift PWM controllers 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.
