FSD176MRT
Green-Mode Fairchild Power Switch (FPS?)
Features
? Advanced Soft Burst-Mode Operation for
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
Description
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), 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 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.
Output Power Table
? 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
