PMICs power any single or dual core ARM processors
The DA9061 and DA9062 PMICs can be powered from a single cell Li-Ion battery or a 5V supply and are designed to meet the minimum requirements in a system for core, memory, peripherals and IO supplies. Each PMIC can power single or dual-core system processors or, when combined with Dialog’s multi-phase sub-PMICs, seamlessly power complete multicore systems requiring greater than 20A on the core supply.
Applications include handheld consumer, industrial embedded, smart home and automotive systems.
“Effective and efficient power management has a tangible effect on the user’s experience with mobile computing devices and embedded electronics,” said Paul Wheeler, Vice President ASSP Mobile Systems at Dialog. “The DA9061 and DA9062 PMICs feature power-saving technology that provides our customers with very competitive power management solutions for a wide range of system requirements.”
The 8.5A DA9062 system PMIC has four powerful switching buck regulators, two of which can be merged to deliver 5A for core processors. Another buck regulator can be used for efficient DDR3 memory termination. The buck regulators operate at 3MHz to allow the use of small external components. This, with the small QFN40 package, ensures the highest power density for the end product.
Maximum energy saving can be achieved by employing the programmable and flexible sequencing power-state manager to control the buck output using Dynamic Voltage Scaling (DVS). Output voltages down to 0.3V can be realized. Where fewer supply rails are needed, further cost savings can be made by using the 6A DA9061 PMIC. This has fewer features and contains one less DC-DC supply.
Evaluation boards with Dialog’s SmartCanvas graphical user interface (GUI) are available to optimize PMIC configuration during product development.
Available in high volume production quantities, both PMIC devices are packaged in a low cost QFN package. The QFN package option with its exposed pad ensures the devices run cooler than alternatives on the market. Pre-programmed standard variants are now available in automotive AEC Q100 G3 and industrial grade options to power popular single and multicore System-on-Chip solutions.
