DA9141-A数据手册Renesas中文资料规格书

描述 Description

The DA9141-A is a high efficiency, automotive grade, high current, quad-phase, step down DC-DC (Buck) converter with integrated switching FET's.The device can drive loads up to 40 Amps and is well suited for powering high performance AI/graphics processor cores in today’s complex automotive SoCs.

The device has an input voltage range of 2.8 V to 5.5 V and an output voltage range of 0.3 V to 1.3 V, making it suitable for a wide variety of low voltage systems.The DA9141-A only requires a minimum number of discrete components to operate, delivering a highly optimized BoM and footprint.

The DA9141-A device is part of the Dialog family of Flexible, Scalable, Reliable Automotive grade PMICs enabling an “Exact Fit” power solution. It is available in a 4.5mm x 7.0mm 60-pin FC-BGA package. A commercial grade version is also available (DA9141).
