Dialog Semiconductor has released the DA914X-A product family comprising of efficient, high current, automotive grade, step down DC-DC (Buck) converters.

The DA914X-A devices deliver current levels, up to 40 amps, which according to the company is a significantly better alternative to power solutions that require a combination of a power controller and discrete FETs.

The family of devices integrates power FETs and all required control logic into a highly integrated monolithic device. Few external components are required for operation, enabling extremely low system BoM costs and solution footprints below 170 mm2. The devices have been designed to be extremely power efficient, and as a result reduce the thermal design challenges of powering complex automotive SoCs with very high current requirements.

This makes the product line suitable for powering graphics or AI embedded processors used in machine learning and vision applications for next generation autonomous vehicles.

The DA914X-A family currently includes two devices. The DA9141-A operates as a single-channel, quad-phase buck converter, delivering up to, 40A output current. The DA9142-A operates as a single-channel, dual-phase buck converter, delivering up to, 20 A 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 wide variety of low power systems.

“As electronics in automobiles continue to demand higher performance heterogeneous processing capability, the requirement for cost effective, space saving power solutions becomes more and more critical,” said Tom Sandoval, Senior VP, GM Automotive Business Segment, Dialog Semiconductor. “The DA914X PMIC family of products offers automotive customers market leading high current power delivery solutions for multi-core automotive SoCs with embedded high-performance graphics or AI processor cores.”
