SMPS Power Switch
The FSL206MR integrated Pulse Width Modulator (PWM) and SenseFET is specifically designed for high-performance offline Switch Mode Power Supplies (SMPS) with minimal external components. This device is integrates high-voltage power regulators that combine an avalanche-rugged SenseFET with a current mode PWM control block.
The integrated PWM controller includes: 7.8V regulator for no bias winding, Under-Voltage Lockout (UVLO) Protection, Leading-Edge Blanking (LEB), an optimized gate turn-on/turn-off driver, EMI attenuator, Thermal Shutdown (TSD) protection, temperature- compensated precision current sources for loop compensation, and fault-protection circuitry such as; Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over- Current Protection (AOCP) and Line Under-Voltage Protection (LUVP). During startup, the FSL206MR offers good soft-start performance.
