PM6680A evaluation kit

dual step-down controller with auxiliary voltages

Introduction

PM6680A evaluation kit order code: STEVAL-ISA053V2.

The PM6680A is a dual step-down controller with adjustable output voltages. The PM6680A

evaluation kit is designed to test the performance of the PM6680A by employing a typical

application circuit that 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.
