PM6680 evaluation kit dual step-down controller
with auxiliary voltages for notebook power system
Introduction
PM6680A evaluation kit order code: STEVAL-ISA053V1.
The PM6680 is a dual step-down controller with adjustable output voltages for notebook
computer power systems. The PM6680 evaluation kit is designed to test the performance of
the PM6680 by employing a typical application circuit that allows testing of all PM6680
device functions. The kit 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 output current. Moreover, an internal linear regulator can provide 5 V @ 100
mA peak current.
