Dialog Semiconductor PMIC powers infotainment and connected cars

Dialog Semiconductor DA9210-A power management IC

Dialog Semiconductor has announced the DA9210-A power management IC, a multiphase, automotive-grade, 12A DC-DC buck converter that supplies the high current core rails of microprocessor devices, including those used in next generation infotainment systems.

Designed to meet the functional, quality and reliability demands of car makers and their customers, it is optimised for the supply of CPUs and GPUs, and can support load currents of up to 12A in single-chip configuration and 24A in dual parallel configuration.

The PMIC’s efficiency over a wide output range is said to make it suitable for powering some of the latest and most demanding innovations of today’s connected cars, from infotainment and navigation systems to full-scale integrated cockpits and future heads-up displays.

“The rapid pace of automotive technology integration and convergence is demanding more from the components that comprise tomorrow’s connected cars,” said Paul Wheeler, vice president for mobile systems at Dialog Semiconductor. “The DA9210-A addresses these new demands and allows automakers the flexibility and performance they need to develop the very latest in connected car technology.”

The DA9210-A is the second generation of its predecessor, the DA9210 buck converter, which is sold into the high-volume smartphone market. The automotive-grade version of the converter is said to have been well received by manufacturers, which can now take advantage of its capabilities to enable infotainment systems in connected vehicles.

Accepting input voltages from 2.8 to 5.5V DC, the device delivers an output voltage between 0.3 and 1.57V, with ±2.5% output voltage accuracy. It has 3MHz nominal switching frequency to reduce external component height and footprint and adjustable soft start. Operating temperature is between -40 and +85˚C.

It is fully AEC-Q100 grade three qualified, comes in a 42 WL-CSP package and is available now.
