Austin, Tex.—Analog Devices' ADP1043 digital power controller helps designers quickly implement energy-efficient AC/DC and isolated DC/DC supply designs for high-reliability server, storage, and communications infrastructure equipment.
The ADP1043 secondary-side digital PWM power control and management chip provides designers with a highly integrated circuit architecture and the flexibility to configure system power-supply parameters in a matter of minutes using an intuitive graphical user interface (GUI). Thus design engineers with no prior programming experience can quickly adjust power functions such as frequency, timing, voltage settings, and protection limits. "Analog Devices defined the GUI and the architecture of the ADP1043 to help today's power design engineers develop intelligent, adaptable power management solutions that accurately report parametric information in real time, without requiring the designer to program in C++ or other languages," said Peter Henry, vice president and general manager for Power Management Products.
The ADP1043 uses an application-specific, on-chip digital control engine that works with the GUI and an industry-standard I2C interface. The chip, which integrates circuitry for isolated power conversion, housekeeping, and monitoring functions, includes a 7-output PWM; on-board memory for program and data storage; the choice of traditional analog or open-standard digital current share schemes for parallel power supply operation; MOSFET "OR-ing" control for redundant power supply operation, and differential voltage sensing and trimming—all of which can be programmed and adjusted via the IC interface.
The ADP1043 chip will be available for general sampling in May 2008 and will be available in production quantities in August. The ADP1043, in a 32-pin LFCSP (5-by-5 mm package) is priced at $4.50 per unit in 1000-piece quantities. For more information, click here.
