Description

The PM6680 is a dual step-down controller with

adjustable output voltages for notebook computer

power systems. The STEVAL-ISA053V1

demonstration board is designed to test the

performance of the PM6680 by employing a

typical application circuit which allows testing of

all PM6680 device functions. The board features

two switching sections, with (typically) 1.5 V and

1.05 V outputs, from a 6 V to 28 V input battery

voltage. The operating switching frequency of the

two switching sections is 200 kHz / 300 kHz,

respectively. Each switching section delivers more

than 5 A of output current. Moreover, an internal

linear regulator can provide 5 V @ 100 mA peak

current.
