The LTC1922-1 phase shift PWM controller provides all of the control and protection functions necessary to implement a high performance, zero voltage switched, phase shift, full-bridge power converter with synchronous rectification. The part is ideal for developing isolated, low voltage, high current outputs from a high voltage input source. The LTC1922-1 combines the benefits of the full-bridge topology with fixed frequency, zero voltage switching operation (ZVS). Adaptive ZVS circuity controls the turn-on signals for each MOSFET independent of internal and external component tolerances for optimal performance.

The LTC1922-1 also provides secondary side synchronous rectifier control. The device uses peak current mode control with programmable slope comp and leading edge blanking.

The LTC1922-1 features extremely low operating and start-up currents to simplify off-line start-up and bias circuitry. The LTC1922-1 also includes a full range of protection features and is available in 20-pin through hole (N) and surface mount (G) packages.
