Green mode PWM IC

FA5680N / 81N

1. Overview

Datasheet

FA5680/81 is a current mode type switching power supply control IC possible to drive a power MOSFET. Although it is

small 8-pin package, FA5680/81 integrates many functions and so is very suited for saving energy during light load and

reducing number of external parts. Therefore, power supply of high cost performance can be built..

2. Features

• Frequency reduction function improves efficiency at middle load.

• The minimum switching frequency is set to 26k Hz to prevent audio noise.

• Intermittent operation (burst operation) at light load realizes low standby

power.

• Low power consumption by built-in 750V startup circuit.

• Overload protection (FA5680: auto restart, FA5681 latch off) and

overvoltage protection functions are built-in and so small number of

components is required for protective operation.

• Since current detection is negative polarity, overload compensation for AC

line voltage change can be made easily.

5.0±0.25

• Latch off function by external signal is incorporated. The function is suited

for overtemperature protection (OTP) using external thermistor.

• Drive circuit for Power-MOSFET is built-in.

Output current: 1.0 A (sink) / 0.5 A (source)

• Under voltage lockout for Vcc is built-in.

1.27

• Frequency diffusion function achives low EMI.

• Since dynamic self supply (DSS) function is provided, VCC voltage is

supplied from VH pinpin to supply power when no voltage is supplied from

auxiliary winding of transformer.
