STEVAL-ISA053V1 Demonstration board for the PM6680 dual step-down controller with adjustable output voltage for notebook power system
The PM6680 is a dual step-down controller with adjustable output voltages for notebook computer power systems. The STEVAL-ISA053V1 demonstration board is designed to test the performance of the PM6680 by employing a typical application circuit which allows testing of all PM6680 device functions. The board 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 of output current. Moreover, an internal linear regulator can provide 5 V @ 100 mA peak current.
