FSL137MRIN Overview
The FSL137MRIN is an integrated Pulse Width Modulation (PWM) controller and SenseFET specifically designed for offline Switched Mode Power Supplies (SMPS) with minimal external ponents. The PWM controller includes an integrated fixed-frequency oscillator, Line Over-Voltage Protection (LOVP), UnderVoltage Lockout (UVLO), Leading-Edge Blanking (LEB), optimized gate driver, internal soft-start, temperaturepensated...
