KIRCHHEIM/TECK-NABERN, GERMANY: Dialog Semiconductor plc has launched the first in a new family of power management ICs (PMICs) designed to optimise the power efficiency of applications using the Intel Atom processor Z5xx series. The DA6001 provides all power supplies, power management and clock supplies in a single chip.
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 like 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.
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.
Further platform power demands are supplied by six high performance, low dropout (LDO) voltage regulators, using Dialog's patented Smart Mirror technology, removing 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 divisions PLLs.
Two analog 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.
