Description
The FSL137MRIN is an integrated Pulse Width Modulation (PWM) controller and SenseFET specifically designed for offline Switched Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fixed-frequency oscillator, Line Over-Voltage Protection (LOVP), Under Voltage Lockout (UVLO), Leading-Edge Blanking (LEB), optimized gate driver, internal soft-start, temperaturecompensated precise current sources for loop compensation, and self-protection circuitry.
