FSL127H

Green Mode Fairchild Power Switch (FPS™)

Features

Description

The highly integrated FSL127H consists of a current

mode Pulse Width Modulator (PWM) and an avalanche-

rugged 700V SenseFET. It is specifically designed for

high-performance offline Switch Mode Power Supplies

(SMPS) with minimal external components.

Built-in 5ms Soft-Start Function

Internal Avalanche-Rugged 700V SenseFET

Low Audio Noise

High-Voltage Startup

The integrated PWM controller features include a

proprietary green-mode function that provides off-time

modulation to linearly decrease the switching frequency

at light-load conditions to minimize standby power

consumption. To avoid acoustic noise problems, the

minimum PWM frequency is set above 18KHz. This

green-mode function enables the power supply to meet

international power conservation requirements. With the

internal high-voltage startup circuitry, the power loss

due to bleeding resistors is also eliminated. To further

reduce power consumption, the PWM controller is

manufactured using the BiCMOS process, which allows

an operating current of only 3.5mA.

Fixed PWM Frequency at 100KHz

Linearly Decreasing PWM Frequency to 18KHz

Peak-Current-Mode Control

Cycle-by-Cycle Current Limiting

Leading-Edge Blanking (LEB)

Synchronized Slope Compensation

Internal Open-Loop Protection (OLP)

V_DDUnder-Voltage Lockout (UVLO)

V_DDOver-Voltage Protection (OVP)

Constant Power Limit (Full AC Input Range)

Internal OTP Sensor with Hysteresis

The FSL127H built-in synchronized slope compensation

achieves stable peak-current-mode control. The

proprietary external line compensation ensures

constant output power limit over a wide AC input

voltage range, from 90V_ACto 264V_AC

Applications

The FSL127H provides many protection functions. In

addition to cycle-by-cycle current limiting, the internal

open-loop protection circuit ensures safety when an

open-loop or output short-circuit failure occurs. PWM

output is disabled until V_DDdrops below the UVLO lower

limit, when the controller starts up again. As long as V_DD

exceeds ~28V, the internal OVP circuit is triggered.

General-purpose switch-mode power supplies and

flyback power converters, including:

SMPS for VCR, SVR, STB, DVD & VCD Player,

Printer, Facsimile, & Scanner

Adapter for Camcorder

Compared to a discrete MOSFET and controller or RCC

switching converter solution, the FSL127H reduces total

component count, design size, and weight while

increasing efficiency, productivity, and system reliability.

These devices provide a basic platform well suited for

design of cost-effective flyback converters.
