Description
The FSL136MR integrated Pulse Width Modulator (PWM) and SenseFET is spec ifically designed for high- performance offline Switch-Mode Power Supplies (SMPS) with minimal external components. FSL136MR includes integrated high-voltage power switching regulators that combine an avalanche-rugged SenseFET with a current-mode PWM control block. The integrated PWM controller includes: 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 FSL136MR offers good soft-start performance. When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSL136MR 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 device may not function or be operable above the recommended operating conditions 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.
