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.
