DA6021

Ultra flexible power sequencer

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 6 high performance low dropout (LDO) voltage regulators using Dialog’s patented Smart Mirror™ technology for very low quiescent current. It includes 11 internal power switches and the control logic for 9 external switching devices. These include in-rush current control for platform power distribution simplification.

Six fully integrated high efficiency DC-DC buck converters provide current to 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 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.

Two high efficiency buck converters with integrated SVID interface running IMVP-7 protocol. These two quad phase DC/DC regulators generate the voltages for CPU and graphic cores.

One dual phase buck regulator for memory supply supporting DDR3 L and LP memory types

3 single phase buck regulators supplying 1.0V, 1.05V and 1.8V towards the platform
