DA6001

Highly integrated power and Clock supply IC for new

generation Intel® Atom™ processor

The DA6001 is a highly integrated system controller, designed to support the Intel® Atom™

Z5xx series platform. The DA6001 provides all power supplies, power management and clock

supplies in a single chip, and has been optimized to deliver enhanced power efficiency to the

platform.

Integrated power management

Sourcing Dialog Semiconductor’s DA6001 with a single supply voltage the device provides, low

noise supplies to all platform voltage domains and provides current to supply additional system

DDR2 memory as well as the firmware hub memory.

The DA6001 integrates six high performance low dropout (LDO) voltage regulators using Dialog’s

patented Smart Mirror™ technology. This ensures very low quiescent current consumption and high

power supply rejection, removing the need for a low power mode and simplifying power control in

the system.

Dialog Semiconductors DA6001 includes a high efficiency DC-DC buck controller which is designed

according to Intel® Atom™ processor IMVP-6 specification, providing the core voltage to the CPU

via its external FETs. The enhanced Intel SpeedStep technology is controlled via the voltage ID

(VID) interface. A fully integrated high efficiency DC-DC buck converter sources the hardware

engines of the Intel Atom platform. A third high efficiency DC-DC buck converter with external FETs

provides high current to the SCH core and the FSB of the Intel® Atom™ platform. A further DC-DC

buck converter with external FETs provides energy to the internal as well as to the external system

memory.

The DA6001 also provides the reference mid voltage for proper

DDR2 operation. It also includes a push-pull source to terminate

DDR2 address or data memory lines if necessary.

Being input voltage independent, a charge pump is integrated to

generate the 5V domain even if the input voltage drops below 5V.

The power domain architecture has been carefully optimized to

deliver enhanced power efficiency to the processor at lowest

power dissipation, thereby maximizing battery life time and

reducing thermal impact.
