Automotive-grade, multiphase DC-DC buck converter outputs 12A

January 19, 2017 // By Graham Prophet
Dialog Semiconductor’s DA9210-A power management IC (PMIC) is 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 in connected cars.

Accepting input voltages from 2.8 to 5.5 VDC, the DA9210-A delivers an output voltage between 0.3 and 1.57V, with ±2.5% output voltage accuracy. It features 3 MHz nominal switching frequency to minimize external component height and reduce solution footprint, adjustable soft start, and is designed to operate between -40° and +85°C. The DA9210-A is fully AEC-Q100 grade 3 qualified and comes in a 42 WL-CSP package.


DA9210-A is designed to meet the functional, quality and reliability demands of car makers. It is optimized 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 high efficiency over a wide output range makes it suitable for powering infotainment and navigation systems through to full-scale integrated cockpits and future heads-up displays (HUDs). The DA9210-A is the second generation, automotive-grade of its predecessor, the DA9210 buck converter, which has found application in high-volume smartphones.
