LT3753EFE#PBF

LT3753 is a current mode PWM controller optimized for an active clamp forward converter topology, allowing upto 100V input operation. A programmable volt-second clamp allows primary switch duty cycles above 50% for high switch, transformer and rectifier utilization. Active clamp control reduces switch voltage stress and increases efficiency. A synchronous output is available for controlling secondary side synchronous rectification. It is widely used in application such as industrial, automotive and military systems, 48V telecommunication isolated power supplies etc.
