Description

Each product in the FSDx0365RN (x for L, M) family consists

of an integrated Pulse Width Modulator (PWM) and Sense

FET, and is specifically designed for high performance 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 inte-

grated 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 compensation and fault protection circuitry. When com-

pared to a discrete MOSFET and controller or RCC switching

converter solution, the FSDx0365RN devices reduce total

component count, design size, weight while increasing effi-

ciency, productivity and system reliability. Both devices pro-

vide a basic platform that is well suited for the design of cost-
