General Description

The DA6021 PMIC is a monolithic single chip power management IC for the next generation Intel® Atom™

processor. It provides all power supplies for tablet PC’s and can also be used in multiple embedded

applications as well as Netbooks and Nettops. It is designed to support platforms based on Intel’s new

Atom processor series, including DDR3 memory and various peripherals.

Integrated power management

Dialog Semiconductor’s new 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. Dependant on the input voltage (single battery cell or 5V DC supply) the buck regulators will run preferably at 6MHz.

Ultra flexible power sequencer

The ultra flexible power sequencer takes care of the complete platform start-up, state-transitioning and power-down procedure. The DA6021 operates autonomously

and reduces the power consumption when entering stand-by or power down mode. The DA6021 is fully programmable and allows adapting to all Intel Atom

processor and platform sequences. The OTP programmed power sequence is copied into operational registers during power-up. Those registers can be overwritten

by EEPROM after initial OTP copy routine or via operational processor.

Auxiliary function

An analogue to digital converter (ADC) with 10-bit resolution combined with a multi-channel input multiplexer is implemented, which allows to measure the input

supply voltage, battery ID, PMIC die temperature as well as 5 battery pack & system temperatures. The number of external components is significantly further reduced

by 16 GPIO’s, 3 channel PWM output signal generators, a multi-input detector with a charger control as well as a programmable IRQ controller.
