Description

General part information

LTC3722 Series

The LTC3722-1/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.The LTC3722-1/LTC3722-2 feature adjustable synchronous rectifier timing for optimal efficiency. A UVLO program input provides accurate system turn-on and turn-off voltages. The LTC3722-1 features peak current mode control with programmable slope compensation and leading edge blanking, while the LTC3722-2 employs voltage mode control.The LTC3722-1/LTC3722-2 feature extremely low operating and start-up currents. Both devices include a full range of protection features and are available in the 24-pin surface mount GN package.ApplicationsTelecommunications, Infrastructure Power SystemsDistributed Power ArchitecturesServer Power Supplies
