RO Associates Intros SYVHC48-2.5-65-1 Half Brick

August 15, 2004 by Jeff Shepard

RO Associates Inc. (Sunnyvale, CA) announced its new ultra-high-efficiency, high-current, half-brick SYVHC48-2.5-65-1 converter with 48 V input and 2.5 V at 65 A. The isolated, fixed-frequency design uses synchronous rectification, an integrated planar transformer and a low-loss multi-layer PCB to provide 65 A of 2.5 Vdc power. The high efficiency of over 89% allows them to be operated in a typical application without a heatsink.

The HC Series includes an integral thermal interface to attach a high-performance cooling system for more demanding environments. The SYVHC48-2.5-65-1 comes in the enhanced half-brick package of 2.42 in x 2.4 in x 0.5 in. The high-current HC modules have double output pins for a low-loss PCB interface. The high-efficiency modules are suitable for low-voltage processors requiring isolation from the 48 V source.

The SyncroVerter HC modules are high-efficiency, constant-frequency, isolated, low-noise converters that operate at full power over a baseplate range of –40 °C to +100 °C and achieve up to 56 W/in³ high-power density. The low-noise, open-frame modules include remote sense, positive and negative on/off logic options, clamping over-voltage protection, standard threaded mounting holes, a trim range of ±10%, and 105 °C over-temperature shutdown protection. Additional features include current limiting, short-circuit protection and transient response. Evaluation boards are available and the modules are UL/CSA/TUV and CE compliant.

Pricing for the SYVHC48-2.5-65-1 in single-piece quantities is $149. For 100-piece quantities, the price is $135. Delivery is stock to six weeks ARO.
