PMIC is ‘most powerful’ for ARM quad core application processors
Dialog Semiconductor has announced what it claims is the most powerful and most integrated configurable power management ic (PMIC) for ARM quad core and dual core application processors.
The DA9063 can deliver up to 12A from its six dc/dc converters, which Dialog says is 24% more than rival devices. It simultaneously powers the processor, external memories, wireless communications, GPS and FM receivers, as well as data modems.
The dc/dc converters can be paralleled to provide 3 and 5A rails, meaning the PMIC is scalable and adaptable for different system requirements in smartphones, tablets and embedded applications. It comes in an 8 x 8mm BGA package to facilitate simple routing, allowing low cost, two layer pcbs to be used for some designs.
"You will not find a similar PMIC in this kind of configuration on the market," Manfred Kogler, product marketing manager at Dialog, told New Electronics. "And with the 5A rail, we are very well positioned for the next generation."
Eleven SmartMirror LDOs are featured, as are 16 GPIOs and two rail switches, in addition to the six main dc/dc outputs. Dialog says that any start up sequence, output voltage and DVC ramps can be programmed, giving unprecedented opportunities for designers to minimise their system energy consumption.
Under the DA9063's supervisory function, the application can be completely powered down and started again. The PMIC further maximises battery life by providing dynamic voltage scaling (DVS), something that Dialog says is not available with discrete solutions.
A supply range of 2.7 to 5.5V enables the use of single cell lithium ion batteries as well as a standard 5V supply or a usb power supply. The operating temperature range is -40 to 85°C.
