Description

The PM6680A is a dual step-down controller with

adjustable output voltages. This demonstration

board is designed to test the performance of the

PM6680A by employing a typical application

circuit which allows testing of all the PM6680A

device functions. The kit features two switching

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

from a 6 V to 36 V input voltage.

The typical operating switching frequency of the

two switching sections is 200 kHz / 300 kHz,

respectively. Each switching section delivers more

than 2.5 A of output current.

Moreover, an internal linear regulator can provide

5 V @ 100 mA peak current.
