FSL4110LR Description
The FSL4110LR is an integrated pulse width modulation (PWM) controller and 1000 V avalanche rugged SenseFET specifically designed for high input voltage offline Switching Mode Power Supplies (SMPS) with minimal external ponents. 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...
