This document introduces the FSL136HR product, including its features such as internal avalanche-rugged senseFET, low power consumption, precise fixed operating frequency, frequency modulation to attenuate EMI, internal startup circuit, built-in soft-start, pulse-by-pulse current limiting, over-voltage protection, overload protection, output-short protection, abnormal over-current protection, internal thermal shutdown function, auto-restart mode, under-voltage lockout.
The FSL136HR is an integrated Pulse Width Modulator (PWM) and SenseFET designed for high-performance offline Switch-Mode Power Supplies (SMPS) with minimal external components. It combines an avalanche-rugged SenseFET with a current-mode PWM control block, offering features such as internal startup circuitry, built-in soft-start, pulse-by-pulse current limiting, and various protection mechanisms including over-voltage, overload, and thermal shutdown.
