Many systems require DC to DC power conversion. Robots typically operate from a battery voltage that ranges from 5 V up to 28 V, which needs to be converted down to various power rails to supply power to the on-board system. ROHM’s BD9x series enables efficient buck-switching DC/DC power conversion from 2.5 V to 100 V input with output currents from 0.5 A to 8 A. The nomenclature shown here indicates the various voltage ranges.
