| HIGH CURRENT DENSITY RoHS-COMPLIANT POINT-OF-LOAD CONVERTERS | |||||
FRAMINGHAM, Mass. - Artesyn Technologies (Nasdaq:ATSN) has launched five new high current density point-of-load (POL) converters that provide dramatic savings in board real estate and external component costs. All five converters are RoHS-compliant members of Artesyn’s C-class family of cost-optimized products, intended for general-purpose computer, storage and networking applications. Three of the new converters are the ultra-small LDO-C series units, offering a choice of 3, 6, and 10 A outputs, while the other two are members of Artesyn’s SIL-C2 family, with 20 A and 40 A outputs. All five converters are the direct result of Artesyn’s ongoing R&D program in very high current density converters – involving specialized component layout, thermal analysis and packaging techniques – and are available with a choice of vertical or horizontal through-hole mounting, and horizontal surface mounting. The 3 A, 6 A and 10 A output LDO-C converters accommodate an input range of 3.0 to 13.8 Vdc and have an output range of 0.59 to 5.1 Vdc. The two higher power SIL-C2 converters have an input range of 4.5 to 13.8 Vdc; the 20 A model – known as the SIL20C2 – has an output range of 0.59 to 5.1 Vdc, while the 40 A rated SIL40C2 has a 0.6 to 5.0 Vdc output range. All five converters provide a flexible and economic solution for powering silicon on densely packed boards, and are also ideal where height is restricted, such as in the latest 1U high rack-mounting equipment. The converters use a fixed frequency switching topology to maximize efficiency, minimize ripple and noise, and ensure a fast transient response. They all employ an open-frame, single-board construction to simply thermal management, are primarily intended for use in forced air environments, and accommodate an ambient operating temperature range of 0 ˚C to +70 ˚C, with suitable derating. The converters are comprehensively protected against short-circuit and overvoltage conditions and carry a full set of international safety approvals, including EN60950 (TÜV Product Service) and UL/cUL60950. Pricing for 1,000-piece quantities is $11.95 US for the SIL20C2 and $18.90 US for the SIL40C2. In similar quantities, the LDO03C, LDO06C and LDO10C are priced at $4.95 US, $7.00 US and $9.85 US respectively. Standard lead-time for all models is stock to 6-8 weeks. | |||||
