Every system requires DC to DC power conversion. Many robots operate from a battery voltage that ranges from 5 V up to 28 V which needs to be converted down to various power rails in order to supply power to various on-board systems. ROHM’s BD9x series of parts covers efficient buck-switching DC/DC power conversion from 2.5 V to 100 V input voltage with output current capability from 0.5 A to 8 A. The part nomenclature shown in the red box on the right side of this page indicates the various voltage ratings of the family.
