High current DC-DC converter slashes footprint, component count
The DA913X-A DC-DC converter family from Dialog Semiconductor integrates a FET to provide high efficiency and small footprint, requiring few external components

Dialog Semiconductor has  launched a highly efficient, high-current, automotive-grade, step-down DC-DC converter family.

The DA913X-A devices require fewer external components than competing solutions, enabling a low system bill of materials (BoM) cost and a reduced solution footprint. The devices operate at efficiency levels above 90 percent, reducing the thermal design challenges for powering high-current rails in a wide range of automotive systems, including infotainment, navigation, telemetry, and Advanced Driver Assistance Systems (ADAS).

The DA913X-A family is comprised of three devices configured as single- or dual-output buck converters.

The DA9130-A operates as a single-channel, dual-phase buck converter, delivering up to a 10 A output current, while the DA9131-A integrates two single phase buck converters, each delivering up to 5 A output current. The DA9132-A also integrates two single-phase buck converters, each delivering up to 3 A output current.
