DA6011

Highly integrated power and clock supply IC for new

generation Intel Atom processor

The DA6011 is a single chip power management and clock companion IC for the Intel®

Atom™ processor E6xx series (formerly codenamed Tunnel Creek). The single chip solution

provides all power and clock supplies as well as system management control. It is designed

to support platforms based on the Intel Atom processor E6xx series, including the IO-hubs.

Integrated power management

Six DC-DC buck converters (three with external FETs and three with integrated FETs) provide

current to the Intel Atom E6xx series platform’s multiple low voltage domains. These highly

efcient buck converters supply the CPU and graphics core and meet Intel IMVP-6 specication.

Furthermore, they power the system memories, the IO-hub and further high current loads of the

The power domain architecture has been carefully optimised to deliver enhanced power efciency

to the platform at the lowest power dissipation, thereby maximising battery life and reducing thermal

impact. The architecture also takes several IO-hubs with its different power requirements into

been implemented. Two inputs can be used to

measure signals manually or automatically.

Operating conditions

Designed with AEC-Q100 specications in mind,

the DA6011 operates between -40 and +85°C

to meet industrial and automotive temperature

The die temperature and the output currents of

each source will be monitored to ensure proper

and safe operation.
