Green-Mode Fairchild Power Switch (FPS™)  
Features  
Description  
The FSD156MRBN is an integrated Pulse Width  
Modulation (PWM) controller and SenseFET specifically  
designed for offline Switch-Mode Power Supplies  
(SMPS) with minimal external components. The PWM  
controller includes an integrated fixed-frequency  
oscillator, 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 FSD series can reduce total cost,

Advanced Soft Burst-Mode Operation for  
Low Standby Power and Low Audible Noise  
Random Frequency Fluctuation (RFF) for Low EMI  
Pulse-by-Pulse Current Limit

Various Protection Functions: Overload Protection  
(OLP), Over-Voltage Protection (OVP), Abnormal  
Over-Current Protection (AOCP), Internal Thermal  
Shutdown (TSD) with Hysteresis, Output-Short  
Protection (OSP), and Under-Voltage Lockout  
(UVLO) with Hysteresis

while  
simultaneously increasing efficiency, productivity, and  
system reliability. This device provides a basic platform  
suited for cost-effective design of a flyback converter.

Notes:  
1. Lead-free package per JEDEC J-STD-020B.  
2. The junction temperature can limit the maximum output power.  
3. 230VAC or 100/115VAC with voltage doubler.  
4. Typical continuous power in a non-ventilated enclosed adapter measured at 50C ambient temperature.  
5. Maximum practical continuous power in an open-frame design at 50C ambient temperature.
