STEVAL-ISA067V1

Dual step-down controller with auxiliary voltages demonstration board based on the PM6681A for industrial system power
  • active Active

This demonstration board is based on the PM6681A, a dual step-down controller with adjustable output voltages that can be used in industrial power systems. The PM6681A demonstration board 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.

The typical operating switching frequency of the two available sections is 200 kHz/300 kHz, respectively. Each switching section delivers more than 2.5 A output current.

An internal linear regulator provides a fixed 5 V output voltage. Another internal linear regulator provides an adjustable output voltage (default 2.5 V). Both linear regulators can deliver up to 100 mA peak current.
