AN-4147 — Design Guidelines for RCD Snubber of Flyback Converters Description
The FSL106MR integrated Pul Width Modulator (PWM) and SenFET is specifically designed for high-performance offline Switch-Mode Power Supplies (SMPS) with minimal external components. FSL106MR includes integrated high-voltage power switching regulators that combine an avalanche-rugged SenFET with a current-mode PWM control block.

The integrated PWM controller features include: Under-Voltage Lockout (UVLO) protection, Leading-Edge Blanking (LEB), a frequency generator for EMI attenuation, an optimized gate turn-on/turn-off driver, Thermal Shutdown (TSD) protection, and temperature-compensated precision current sources for loop compensation and fault protection circuitry. The FSL106MR offers good soft-start performance. When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSL106MR reduces total component count, design size, and weight; while increasing efficiency, productivity, and system reliability. This device provides a basic platform that is well suited
for the design of cost-effective flyback converters.

but still allows the protection mechanism to operate under true overload conditions.
4 I PK Peak Current Limit. Adjusts the peak current limit of the SenFET. The feedback 0.4mA current source is diverted to the parallel combination of an internal 6kΩ resistor and any external resistor to GND on this pin to determine the peak current limit.
5 V STR Startup. Connected to the rectified AC line voltage source. At startup, the internal switch supplies internal bias and charges an external storage capacitor placed between the V CC pin and ground. Once V CC reaches 12V, the internal switch is opened.
6, 7, 8 Drain Drain. Designed to connect directly to the primary lead of the transformer and capable of switching a maximum of 650V. Minimizing the length of the trace connecting the pins to the transformer decreas leakage inductance.
