Product Overview

The LT1952IGN-1#PBF is a single Switch PWM Controller optimized to control the forward converter topology, using one primary MOSFET. It provides synchronous rectifier control, resulting in extremely high efficiency. A programmable volt-second clamp provides a safeguard for transformer reset that prevents saturation. This allows a single MOSFET on the primary side to reliably run at greater than 50% duty cycle for high MOSFET, transformer and rectifier utilization. The devices include soft-start for controlled exit from shutdown and under voltage lockout. A precision 107mV current limit threshold, independent of duty cycle, combines with soft start to provide hiccup short circuit protection. The LT1952 is optimized for micro-power bootstrap startup from high input voltages. The LT1952-1 allows startup from lower input voltages. Programmable slope compensation and leading edge blanking allow optimization of loop bandwidth with a wide range of inductors and MOSFETs.
