The LT3753 is a current mode PWM controller optimized for an active clamp forward converter topology, allowing up to 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. The LT3753 is available in a 38-lead plastic TSSOP package with missing pins for high voltage spacings.
