Analog Devices Inc. (ADI, Wilmington, MA) introduced the ADM1041, a highly-integrated, advanced secondary-side controller targeted for high-availability >300 W ac-dc power supplies used in 24 x 7 communications applications such as computer servers, network routers, hubs and switches, and base stations. Used as a secondary-side power controller, the ADM1041 can replace hundreds of discrete components – up to a 70% reduction in total power supply components.
The ADM1041 provides a fully tested, digitally controlled solution, eliminating the need for manual calibration and adjustment on the secondary-side controller. This enables faster product design cycles (time-to-market), a critical requirement in the data processing and communications markets. The reduction in component count increases the mean time between failure, improving system reliability and power supply quality in high availability 24 x 7 applications, such as network servers and routers.
The ADM1041 is available in a 24-pin QSOP package and is priced at $3.95 per unit in 10,000-piece quantities.
