SMPS Power SwitchGeneral DescriptionThe FSL206MR integrated Pulse Width Modulator (PWM) and SenseFET is specifically designed for highperformance offline Switch Mode Power Supplies (SMPS) with minimal external components. This device is integrated 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. The internal high-voltage startup switch and the burstmode operation with very low operating current reduce the power loss in standby mode. As a result, it is possible to reach power loss of 150mW with no-bias winding and 25mW with bias winding at no-load condition when the input voltage is 265VAC. Product Status/Pricing/Packing
