FSD176MRT

Green-Mode Fairchild Power Switch (FPS™)

Features

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.

. 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 (0.4mA) in Burst Mode

. Internal Startup Circuit

. Internal High-Voltage SenseFET: 650V

. Built-in Soft-Start: 15ms

. Auto-Restart Mode

Applications

. Power Supply for LCD Monitor, STB, and

DVD Combination

Notes:

1. Pb-free package per JEDEC J-STD-020B.

2. The junction temperature can limit the maximum output power.

3. 230V_ACor 100/115V_ACwith 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.
