FSL137MRIN
Green-Mode Fairchild Power Switch (FPS™)
Features
Advanced Soft Burst Mode for Low Standby Power
and Low Audible Noise
Random Frequency Fluctuation (RFF) for Low EMI
Under 50 mW Standby Power Consumption at
265 VAC, No-load Condition with Burst Mode
Pulse-by-Pulse Current Limit
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, Line Over-Voltage Protection (LOVP)
Low Operating Current (0.4 mA) in Burst Mode
Internal Startup Circuit
Internal High-Voltage SenseFET: 700 V
Built-in Soft-Start: 15 ms
Auto-Restart Mode
Applications
Power Supply for Home Appliances, LCD Monitors,
STBs, and DVD Players
Description
The FSL137MRIN 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 FSL137MRIN 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 flyback converters.

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