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. STEVAL-ISA053V2
