Description
The FSL156MRIN is an integrated Pulse Width
Modulation (PWM) controller and SenseFET specifically
designed for offline Switched Mode Power Supplies
(SMPS) with minimal external components. The PWM
controller includes an integrated fixed-frequency
oscillator, Line-Over Voltage Protection (LOVP), Under-
Voltage Lockout (UVLO), Leading-Edge Blanking (LEB),
optimized gate driver, internal soft-start, temperature-
compensated precise current sources for loop
compensation, and self-protection circuitry. Compared
with a discrete MOSFET and PWM controller solution,
the FSL156MRIN reduces total cost, component count,
size, and weight; while simultaneously increasing
efficiency, productivity, and system reliability. This
device provides a basic platform suited for cost-effective
design of a flyback converter.
