Description
The FSL106HR integrated Pu lse Width Modulator (PWM) and SenseFET is specifically designed for high- performance offline Switch-Mode Power Supplies (SMPS) with minimal external components. FSL106HR includes integrated high- voltage power switching regulators that comb ine an avalanche-rugged SenseFET with a current-mode PWM control block. The integrated PWM controller includes: Under-Voltage Lockout (UVLO) protec tion, Leading-Edge Blanking (LEB), a frequency generator for EMI attenuation, an optimized gate turn-on/turn-off driver, Thermal Shutdown (TSD) protec tion, and temperature- compensated precision current sources for loop compensation and fault prot ection circuitry. The FSL106HR offers good soft-start performance. When compared to a discrete MO SFET and controller or RCC switching converter solution, the FSL106HR 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.

The devic e may not function or be operable above the recommended operating c onditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
