FSD176MRT
Green-Mode Fairchild Power Switch (FPS™)
Features Description  Advanced Soft Burst-Mode Operation for The FSD176MRT 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), LeadingEdge 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 FSD176MRT can reduce total
cost, component count, size, and weight; while
simultaneously increasing efficiency, productivity, and
system reliability. This device provides a basic platform
for cost-effective design of a flyback converter. Low Standby Power and Low Audible Noise  Random Frequency Fluctuation 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  Low Operating Current (0.4 mA) in Burst Mode
 Internal Startup Circuit
 Internal High-Voltage SenseFET: 650 V
 Built-in Soft-Start: 15 ms
 Auto-Restart Mode
Applications
 Power Supply for LCD Monitor, STB, and
DVD Combination Ordering Information

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