Description
The FSL126MR integrated Pulse Width Modulator
(PWM) and SenseFET is specifically designed for high-
performance offline Switch-Mode Power Supplies
(SMPS) with minimal external components. FSL126MR
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
FSL126MR offers good soft-start performance. When
compared to a discrete MOSFET and controller or RCC
switching converter solution, the FSL126MR 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.
