1. General Description

The DA6021 PMIC is a monolithic single chip power management IC for Intel? Atom? Z3000 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 Z3000 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 for the platform. All nine regulators are designed to support external component height of 1mm.

Ultra flexible power sequencer

The ultra-flexible power sequencer takes care of the complete platform start-up, state-transitioning and powerdown 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 adaption to all Intel Atom

processor Z3000 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

allows measurement of the input supply voltage, battery ID, PMIC die temperature as well as 5 battery pack &

system temperatures. The number of external components is significantly reduced due to the integration of 16

GPIO’s, 3 channel PWM output signal generators, a multi-input detector with a charger control as well as a

programmable IRQ controller.
