Description
The FSL106HR integrated Pulse Width Modulator
(PWM) and SenseFET is specifically designed for high-
performance offline Switch-Mode Power Supplies
(SMPS) with minimal external components. FSL106HR
includes integrated high-voltage power switching
regulators that combine an avalanche-rugged
SenseFET with a current-mode PWM control block.
The integrated PWM controller includes: Under-Voltage
Lockout (UVLO) protection, Leading-Edge Blanking
(LEB), a frequency generator for EMI attenuation, an
optimized gate turn-on/turn-off driver, Thermal
Shutdown (TSD) protection, and temperature-
compensated precision current sources for loop
compensation and fault protection circuitry. The
FSL106HR offers good soft-start performance. When
compared to a discrete MOSFET and controller or RCC
switching converter solution, the FSL106HR reduces
total component count, design size, and weight; while
increasing efficiency, productivity, and system reliability.
This device provides a basic platform that is well suited
for the design of cost-effective flyback converters.
