The DA9131 is a high-efficiency, dual-channel, step-down DC/DC (buck) converter with integrated switching FETs delivering 5A per channel. The device can operate at efficiency levels above 90%, reducing the thermal design challenges of powering high current rails in a wide range of high-performance electronic systems.
The DA9131 device has an input voltage range of 2.5V to 5.5V and an output voltage range of 0.3V to 1.9V, making it suitable for a wide variety of low voltage systems. The DA9131 only requires two small 0.10µH inductors, delivering a highly optimized BOM and footprint. Output voltages above 1.9V are supported with an external resistor divider.
The DA9131 device is part of the Renesas family of flexible, scalable, reliable automotive systems and sub-PMICs, enabling an "Exact-Fit" power solution. It is available in a 3.3mm x 4.8mm 24-pin FC-QFN wettable flank package. An automotive-grade version is also available (DA9131-A).
