Description
General part information
LT3753 Series
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.ApplicationsIndustrial, Automotive and Military Systems48V Telecommunication Isolated Power Supplies
