FSL136MRT • Rev. 1.0.0

FSL136MRT

Green-Mode Fairchild Power Switch (FPS™)

Features

Standby Power and Low Audible Noise

(OLP), Over-Voltage Protection (OVP), Abnormal

Over-Current Protection (AOCP), Internal Thermal

Shutdown (TSD) with Hysteresis, and Under-Voltage

Lockout (UVLO) with Hysteresis

Applications

DVD Combination

Description

The FSL136MRT is an integrated Pulse Width

Modulation (PWM) controller and SenseFET specifically

designed for offline Switch-Mode Power Supplies

(SMPS) with minimal external components. The PWM

controller

includes

an

integrated

fixed-frequency

oscillator, Under-Voltage Lockout (UVLO), Leading-

Edge Blanking (LEB), optimized gate driver, internal

soft-start, temperature-compensated precise current

sources for loop compensation, and self-protection

circuitry. Compared with a discrete MOSFET and PWM

controller solution, the FSL136MRT can reduce total

cost, component count, size, and weight; while

simultaneously increasing efficiency, productivity, and

system reliability. This device provides a basic platform

suited for cost-effective design of a flyback converter.
