LT3753 - Active Clamp Synchronous Forward Controller
- Input Voltage Range: 8.5V to 100V
- Programmable Volt-Second Clamp
- High Efficiency Control: Active Clamp, Synchronous Rectification, Programmable Delays
- Short-Circuit (Hiccup Mode) Overcurrent Protection
- Programmable Soft-Start/Stop
- Programmable OVLO and UVLO with Hysteresis
- Programmable Frequency (100kHz to 500kHz)
- Synchronizable to an External Clock
The LT®3753 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.
