Flexible PMIC targets ARM quad-core processors
The highly integrated and configurable DA9063 power management IC (PMIC) targets ARM quad-core and dual-core application processors. It delivers up to 12 A from its six dc/dc converters, 24% more than its nearest competitor. The device simultaneously powers the processor (the core at up to 5 A plus other processor supplies), external memories, wireless communications (WLAN and Bluetooth), GPS and FM receivers, and data modems. The dc/dc converters can be paralleled to provide 3 and 5A rails.
The PMIC is scalable and adaptable for different system requirements in smartphones, tablets and embedded applications. It comes in an 8 x 8–mm BGA package. The supply range of 2.7 to 5.5–V enables the use of single cell lithium-ion batteries as well as a standard 5–V supply or a USB power supply.The chip has 11 SmartMirror LDOs, 16 GPIOs and two rail switches, in addition to the six main dc/dc outputs. It provides dynamic voltage scaling and its multimode buck converter runs at 3–MHz switching frequency, enabling 1–mm high inductors.
