FSL4110LRN (ON SEMICONDUCTOR)

The FSL4110LRN is a 1000V SenseFET Integrated Power Switch specifically designed for high input voltage offline switching mode power supplies (SMPS) with minimal external components. VCC can be supplied through integrated high-voltage power regulator without auxiliary bias winding. The integrated PWM controller includes a fixed frequency oscillator, under-voltage lockout (UVLO), leading-edge blanking (LEB), optimized gate driver, soft-start, temperature-compensated precise current sources for loop-compensation and variable protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSL4110LR reduces total cost, component count, PCB size and weight; while simultaneously increasing efficiency, productivity and system reliability. This device provides a basic platform for cost-effective design of a flyback converter.
