Dialog Semiconductor has launched the first in a family of power-management ICs (PMICs) designed to optimise the power efficiency of applications using the Intel Atom Z5xx series processor.

The DA6001 provides all power, power-management and clock supplies in a single chip.

The company claims that the PMIC improves battery life, simplifies design, improves system reliability, requires less than half the board space and cuts the bill of materials compared with using discrete power-management parts.

The DA6001 supports the Intel Atom processor for embedded computing applications, automotive applications such as in-vehicle infotainment, netbooks and mobile internet devices.

The device family will expand to support future Intel Atom processors and platforms for the embedded and portable space.

Juergen Friedel, vice-president and general manager, said: ‘The Intel Atom processor is power optimised, delivering robust performance per watt for cost-effective embedded applications.

‘The DA6001 – as a companion IC – adds the ability to minimise power consumption across the complete platform, not just the processor, without adding the cost and complexity of multiple power-management and clocking devices to achieve this.’ Ton Steenman, vice-president of the Digital Enterprise Group and general manager of the Low-Power Embedded Products Division, said: ‘Embedded developers are designing products used in thermally constrained environments and require very low-power solutions.

‘The combination of the Intel Atom processor Z5xx series and the DA6001 provides our customers with more choice in the way they can deliver extremely power-efficient solutions to a variety of embedded market segments.’ 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, the FSB, both internal and external system memory and the CPU core, meeting IMVP-6 specification for the Intel Atom processor.

Further platform power demands are supplied by six high-performance, low-dropout (LDO) voltage regulators using Dialog’s patented Smart Mirror technology, eliminating the need for a low-power mode and 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 three separate fractional division 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 will be available from June 2009, with volume production and AEC-Q100-qualified volume parts for automotive applications in the second half of 2009.
