Maximum Output Power Notes: 1. Typical continuous power in a non-ventilated enclosed adapter measured at 50°C ambient. 2. Maximum practical continuous power in an open frame design at 50°C ambient. 3. 230 VAC or 100/115 VAC with doubler. Application - SMPS for LCD monitor and STB - Adaptor Description The FSDM0565RB is an integrated Pulse Width Modulator (PWM) and Sense FET specifically designed for high performance offline Switch Mode Power Supplies (SMPS) with minimal external ponents. This device is an integrated high voltage power switching regulator which bine an avalanche rugged Sense FET with a current mode PWM control block. The PWM controller includes integrated fixed frequency oscillator, under voltage lockout, leading edge blanking (LEB), optimized gate driver, internal soft start, temperature pensated precise current sources for a loop pensation and self protection circuitry. pared with discrete MOSFET and PWM controller solution, it can reduce total cost, ponent count, size and weight simultaneously increasing efficiency, productivity, and system reliability. This device is a basic platform well suited for cost effective designs of flyback converters. Typical Circuit AC IN DC OUT Vstr PWM Vfb Drain Vcc Sou...
