Pin No.

Description

Equivalent Circuit

FCP

Current limiter circuit frequency characteristics

correction

Connect a capacitor (about 0.01

μF to 0.1μF)

between this pin and ground.

The output duty is determined by comparing the

voltage at this pin with the PWM oscillator

waveform.

Phase comparator output

The phase error is converted to a pulse duty and

output from this pin.

Error amplifier input

Error amplifier output

FGFIL

FG filter

This pin is normally left open. If noise on the FG

signal is a problem, connect a capacitor (about

20pF or smaller) between this pin and ground.
