Powering those “pizza-box” apps

The SBLP65-1012G, a 65W, 12Vout, ac-dc power supply, delivers a quasi-resonant zerovoltage switching topology that offers efficiencies of 80 to 85% at full-power operation and at load conditions as low as 10%.

Developed by Power-One, the SBLP65-1012G provides 60W with only convection cooling and full-rated power with less than five CFM airflow. These reduced cooling requirements facilitate greater overall-system layout flexibility. The reason behind this enhancement is that the SBLP65 doesn’t have to be located directly adjacent to a system fan. In fact, the SBLP65 devices may completely eliminate the need for a dedicated power-supply cooling fan, especially in space-constrained 1-U “pizza-box” applications.

Additional features include 75W peak power capability, 90-264Vac wide-range input, and remote sense. It comes in a compact 51 x 102mm footprint, and has a low-profile 1-U compliant 1.3-in. (33mm) height. On top of that, it meets six-substance RoHS compliance. The rugged product also complies with EN61000-4-2 level 4 (ESD), EN61000-4-3 (RF), EN61000-4-4 level 3 (FastTransient/Burst), and EN61000-4-5 class 3 (Surge).
