Description

This demonstration board is based on the

PM6681A, a dual step-down controller with

adjustable output voltages that can be used in

industrial power systems. The PM6681A

demonstration board allows testing all the

device's functions and provides two switching

sections, with (typically) 3.3 V (OUT1) and 1.8 V

(OUT2) outputs from 5.5 V to 36 V input voltage.

The typical operating switching frequency of the

two available sections is 200 kHz/300 kHz,

respectively. Each switching section delivers more

than 2.5 A output current.

An internal linear regulator provides a fixed 5 V

output voltage. Another internal linear regulator

provides an adjustable output voltage (default 2.5

V). Both linear regulators can deliver up to 100

mA peak current.
