RO Associates Debuts SYVHC48-1.8-80-1 Modules

October 22, 2003 by Jeff Shepard

RO Associates Inc. (Sunnyvale, CA) announced the release of a new ultra-high-efficiency, high-current half brick with 48V input and 1.8V at 80A. The isolated, fixed-frequency, state-of-the-art design uses synchronous rectification, an integrated planar transformer, and a low-loss multi-layer PCB to provide 80A of 1.8Vdc power. The high efficiency of over 88% allows them to be operated in a typical application without a heat sink. The HC Series includes an integral thermal interface to attach a high-performance cooling system for more demanding environments.

The SYVHC48-1.8-80-1 comes in the enhanced, half-brick package of 2.42in x 2.4in x 0.5in. The high-current HC modules have double output pins for a low-loss PCB interface. The SyncroVerter HC modules are high-efficiency, constant-frequency, isolated, low-noise converters that operate at full power over a base plate range of –40°C to +100°C, and achieve up to 50W/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 -15 to +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 SYVHC48-1.8-80-1 in single-piece quantities is $149; for 100-piece quantities the price is $135. Delivery is stock to six weeks ARO.
