PM6686 is a dual step-down controller with adjustable output voltages, adjustable LDO and charge pump circuit for notebook power systems. This application note describes the PM6686 demonstration kit, which represents a typical application circuit, and allows testing of all the functions of the PM6686 device. The demonstration kit provides two switching sections with 5 V (OUT1) and 3.3 V (OUT2) outputs from 8 V to 28 V input battery voltage. The operating switching frequency of the two sections is 400 kHz and 300 kHz, respectively. Each switching section delivers more than 5 A of output current. An internal linear regulator can provide 5 V at 100 mA peak current. The charge pump circuit provides an auxiliary 12 V output voltage.
