Dialog Semiconductor Introduces Newest PMIC Family for High-Performance Automotive AI SoCs

     Dialog Semiconductor, a leading provider of battery management, AC/DC power conversion, Wi-Fi, Bluetooth Low Energy (BLE), and industrial IC solutions, announces the launch of a new ultra-high-efficiency, high-current, automotive-grade, step-down DC- DC (Buck) converter DA914X-A product series.

     The DA914X-A device offers unprecedented current ratings of up to 40A, making the DA914X-A a significantly better alternative to power products that require both a power controller and discrete FETs. The DA914X-A series incorporates power FETs and all required control logic into a highly integrated and efficient single chip. Only few external components are required to operate, resulting in a very low system BOM cost and a solution size of less than 170 mm2. This family of devices is extremely energy efficient, reducing thermal challenges when supplying high currents to complex automotive SoCs. This makes the product family ideal for powering graphics or AI embedded processors in machine learning and vision applications in next-generation autonomous vehicles.

     The DA914X-A family currently includes two devices. The DA9141-A is a single-channel, four-phase buck converter capable of delivering up to 40A of output current. The DA9142-A is a single-channel, dual-phase buck converter capable of delivering up to 20A of output current. All devices have 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 them suitable for a variety of low-power systems.

     "As automotive electronics continue to demand higher-performance heterogeneous processing capabilities, the need for cost-effective and space-saving power solutions becomes increasingly critical," said Tom Sandoval, senior vice president and general manager of the Automotive Business Unit at Dialog Semiconductor. "The DA914X-A PMIC family provides automotive customers with a market-leading high-current power supply solution well suited to the needs of multi-core automotive SoCs with embedded high-performance graphics or AI processor cores."
