Description

General part information

DA9131-A Series

The DA9131-A is a high-efficiency, automotive-grade, 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 automotive systems such as navigation systems, infotainment, telematics, Advanced Driver Assistance Systems (ADAS), or any automotive high-performance processing system requiring efficient, high current, power delivery.

The DA9131-A 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-A 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-A 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 Industrial/commercial grade version is also available (DA9131).
