Dialog Semiconductor has come up with a range power management ICs for Intel Atom processor Z5xx series-based embedded designs, providing all power supplies, power management and clock supplies in a single chip.

From a single supply voltage, the DA6001 provides low noise supplies to all platform voltage domains and current for system DDR2 memory.

Four DC/DC buck converters power the platform hardware engine, the SCH core and FSB, both internal and external system memory and the CPU core - meeting IMVP-6 specification for the Intel Atom processor.

There are also six low dropout (LDO) voltage regulators, which are designed to remove the need for a low power mode and thereby simplifying power control in the system.

A dedicated push-pull LDO is integrated into the device to terminate the address lines of the external RAM, further minimising external components.

The DA6001 includes a clock synthesiser/driver according to Intel’s CK610 specification providing all the necessary clocks via 3 separate fractional divisions PLLs.

Two analogue signal inputs can be multiplexed to a 10-bit ADC converter for signal measurements and a charge pump, which is integrated to generate the 5V reference domain even if the input voltage drops below 5V.

An autonomous state machine manages the complete system start-up and shutdown procedures as well as the state transitions of the Intel Atom processor during all operational modes.

Engineering samples are available from June 2009 with volume production and AEC-Q100 qualified volume parts, for automotive applications, in the second half of 2009.
