Application note
Dual step-down controller with auxiliary voltages
for industrial system power

Introduction
The PM6681A is a dual step-down controller with adjustable output voltages that can be
used in industrial power systems and this demonstration kit represents a typical application
circuit. The PM6681A demonstration kit allows testing all the device's functions and provides
two switching sections, with (typically) 3.3 V (OUT1) and 1.8 V (OUT2) outputs from 5.5 V to
36 V input voltage
