Highly Integrated Power Management IC for New Generation Intel Atom Processor

The DA6021 uses a single supply voltage at a wide range of input voltage and provides low noise supplies to all SoC voltage domains, DDR3 memory, and many peripherals. The DA6021 integrates six high-performance low dropout (LDO) voltage regulators using Renesas' patented Smart Mirror™ technology for very low quiescent current. It includes 11 internal power switches and the control logic for nine external switching devices. These include inrush current control for platform power distribution simplification.

Six fully integrated high-efficiency DC/DC buck converters provide current to the Intel® Atom™ platform’s various low-voltage domains as well as to the memory and the peripherals. Two buck-boost and one boost converter also supply energy towards the platform. All nine regulators are designed to support an external component height of 1mm. Dependent on the input voltage (single battery cell of 5V DC supply), the buck regulators will run preferably at 6MHz.
