Welcome to SHENZHEN HUAXUANYANG ELECTRONIC CO.,LTD
Synchronous step-down DC/DC
Once the main power is efficiently converted from AC to DC, industrial systems usually need further DC/DC conversion to get the right subsystem supply voltage. For the IC on the motherboard, the logic supply voltage can be as low as 1.2 V.
