Description

The FSDx0265RN(x stands for M, H) are integrated Pulse

Width Modulators (PWM) and Sense FETs specifically

designed for high performance offline Switch Mode Power

Supplies (SMPS) with minimal external components. Both

devices are integrated high voltage power switching regula-

tors which combine an avalanche rugged Sense FET with a

current mode PWM control block. The integrated PWM con-

troller features include: a fixed oscillator with frequency

modulation for reduced EMI, Under Voltage Lock Out

(UVLO) protection, Leading Edge Blanking (LEB), opti-

mized 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 compared to a discrete MOSFET and controller or

RCC switching converter solution, the FSDx0265RN reduce

total component count, design size, weight and at the same

time increase efficiency, productivity, and system reliability.

Both devices are a basic platform well suited for cost effec-

tive designs of flyback converters.
