The DA913X-A product family with fully integrated FETs boasts high efficiency and small footprints, requiring few external components
Dialog Semiconductor announces the DA913X-A product family, a new line of highly efficient, high-current, automotive-grade, step-down DC-DC (Buck) converters.
The highly integrated DA913X-A devices require fewer external components than competing solutions, enabling a low system BoM cost and a reduced solution footprint. The devices operate at efficiency levels above 90%, 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. 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. All devices have an input voltage range of 2.5 V to 5.5 V and an output voltage range of 0.3 V to 1.9 V, making them suitable for a wide variety of low-voltage systems. Output voltages above 1.9 V are supported with an external resistor divider.
The DA913X-A products include several key features to meet the needs of today’s complex automotive electronics systems:
The DA9130X-A devices are AEC-Q100 Grade 2 qualified and are available in a 3.3 mm × 4.8 mm a 24-pin FC-QFN wettable flank package. Industrial/commercial grade versions are also available.
