Functional Pin Description

Pin Name

Pin Function

VOUT

Regulated output voltage.

For best performance, VOUT should be bypassed with a 1μF (min.) low ESR capacitor

as close as possible to the pin.

GND

Ground.

Should be tied to a ground plane for best performance.

SHDN

Active low shutdown input.

A low voltage on SHDN disables the FP6770.

SHDN is not allowed to float.

C-

Flying capacitor negative terminal.

VIN

Input supply voltage.

VIN should be bypassed with a 1μF (min.) low ESR capacitor.

C+

Flying capacitor positive terminal.
