■ Output soft-end

Description

This evaluation board is based on the PM6675AS

device, which consists of a single high efficiency

step-down controller and an independent low-

dropout (LDO) linear regulator.

The constant on-time (COT) architecture assures

fast transient response supporting both

electrolytic and ceramic output capacitors. An

embedded integrator control loop compensates

the DC voltage error due to the output ripple.

Selectable low-consumption mode allows the

highest efficiency over a wide range of load

conditions. The low-noise mode sets the minimum

switching frequency to 33 kHz for audio-sensitive

applications. The LDO linear regulator can sink

and source up to 2 Apk. Two fixed current limits

(±1 A and ±2 A) can be chosen.

An active soft-end is independently performed on

both the switching and the linear regulator outputs

when disabled.
