FSD146MRBN

Green-Mode Fairchild Power Switch (FPS™)

Features

Description

The FSD146MRBN is an integrated Pulse Width

Modulation (PWM) controller and SenseFET 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 FSD146MRBN can reduce total cost, component

count, size, and weight; while simultaneously increasing

efficiency, productivity, and system reliability. This

device provides a basic platform that is well suited 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. Lead-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.
