Description
The FSL116HR integrated Pulse Width Modulator
(PWM) and SenseFET is specifically designed for high-
performance offline Switched-Mode Power Supplies
(SMPS) with minimal external components. FSL116HR
includes
regulators
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
compensated precision current sources for loop
compensation
FSL116HR offers good soft-start performance. When
compared to a discrete MOSFET and controller or RCC
switching converter solution, the FSL116HR 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.
