LT3752MPFE-1#PBF

LINEAR TECHNOLOGY  LT3752MPFE-1#PBF  控制器, PWM, 16V-10.5V电源, 500 kHz, TSSOP-38

The is a current-mode PWM Controller optimized for an active clamp forward converter topology. A DC/DC housekeeping controller is included for improved efficiency and performance. The LT3752 allows operation up to 100V input. 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.
