Dialog Semiconductor’s new DA6011 uses a single supply voltage and provides low noise supplies to all CPU and IO-Hub voltage domains with current management for the system DDR2 and boot SPI flash memory.
The DA6011 integrates 11 high performance low dropout (LDO) voltage regulators, which use Dialog’s patented Smart Mirror™ technology for very low quiescent current, and includes 3 pass devices for platform power distribution simplification.
Six DC-DC buck converters (three with external FETs and three with integrated FETs) provide current to the E6xx platform’s multiple low voltage domains.
These highly efficient buck converters supply the CPU and graphics core and meet Intel IMVP-6 specification. Furthermore, they power the system memories, the IO-hub and further high current loads of the platform.
The power domain architecture has been carefully optimised to deliver enhanced power efficiency 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 account.
The integrated system management controller takes care of the complete platform start-up, state-transitioning and power-down procedures. It operates autonomously and reduces the overall system power consumption when entering stand-by or power down modes.
The flexible state-machine implementation is designed to control E6xx platforms including the Intel Topcliff, OKI Semiconductor ML7223 / ML7213 and ST Microelectronics ConneXt STA2X11 IO-hubs.
An analog to digital converter (ADC) with 10bit resolution combined with an input multiplexer and track and hold circuitry will be implemented. Two inputs can be used to measure signals manually or automatically.
Designed with AEC-Q100 specifications in mind, the DA6011 operates between -40 and +85oC to meet industrial and automotive temperature ranges. The die temperature and the output currents of each source will be monitored to ensure proper and safe operation.
