Analog Devices анонсировала на конференции APEC (Applied Power Electronics Conference, 24-28 февраля 2008, Остин, Техас) цифровые PWM [[контроллеры ADP1043]] для AC-DC и DC-DC преобразователей, используемых в серверах повышенной надежности, системах хранения данных и коммуникационном оборудовании [англ.]
The ADP1043 uses an application-specific, on-chip digital control engine that works in concert with the GUI and an industry-standard I2C interface. The new power control and management device incorporates a highly integrated circuit design that significantly reduces component count compared to competing analog and digital power controllers.
ADP1043 offers extensive integration for optimal system performance
The single-chip ADP1043 integrates on-chip technology for isolated power conversion, housekeeping, and monitoring that enables the practical implementation of more energy efficient power supply designs. The ADP1043 controller’s features include 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 I2C interface.
Availability and pricing
The ADP1043 will be available for general sampling in May 2008 and will be available in production quantities in August 2008. The ADP1043 is priced at $4.50 per unit in 1000-piece quantities and comes in a 32-pin LFCSP (5mm x 5mm) package.
