Description

Each product in the FSDx0265RN (x for M, H) family con-

sists of an integrated Pulse Width Modulator (PWM) and

Sense FET, and is specifically designed for high perfor-

mance off-line Switch Mode Power Supplies (SMPS) with

minimal external components. Both devices are integrated

high voltage power switching regulators which combine an

avalanche rugged Sense FET with a current mode PWM

control block. The integrated PWM controller features

include: a fixed oscillator with frequency modulation for

reduced EMI, Under Voltage Lock Out (UVLO) protection,

Leading Edge Blanking (LEB), an optimized gate turn-on/

turn-off driver, Thermal Shut Down (TSD) protection,

Abnormal Over Current Protection (AOCP) and temperature

compensated precision current sources for loop compensa-

tion and fault protection circuitry. When compared to a dis-

crete MOSFET and controller or RCC switching converter

solution, the FSDx0265RN devices reduce total component

count, design size, weight while increasing efficiency, pro-

ductivity and system reliability. Both devices provide a basic

platform that is well suited for the design of cost-effective

flyback converters.
