Pin Description

36

PD

Phase comparator output (PLL output).

This pin output the phase error as a pulse signal with

varying duty. The output current increases as the duty

becomes smaller.

VREG

EI

Error amplifier in put pin.

EO

Error amplifier output pin.

The output current increases when this output is high.

FC

Control amplifier frequency correction.

Inserting a capacitor (about 5600pF) between this pin

VREG

and ground will stop closed loop oscillation in the

current control system.

The output current response characteristics will be

degraded if the capacitor is too large.
