High Current Density RoHS-Compliant POL Converters

Page Contents:   [ Featured Products | Datasheets | Application Notes | Buy Now ]

High current density RoHS-compliant point-of-load converters provide small footprint solution for space sensitive applications.

With a wide choice of models – spanning 3A to 40A – all with ultra wide input/output voltage ranges, these POL converters have a highly integrated packaging technique that dramatically shrinks module size.

Artesyn 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 these converters are the ultra small LDO-C series units, offering a choice of 3A, 6A and 10A outputs, while the other two are members of Artesyn’s SIL-C2 family, with 20A and 40A 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 3A, 6A and 10A output LDO-C converters accommodate an input range of 3.0 to 13.8V DC and have an output range of 0.59 to 5.1V DC. The two higher power SIL-C2 converters have an input range of 4.5 to 13.8V DC; the 20A model – known as the SIL20C2 – has an output range of 0.59 to 5.1V DC, while the 40A rated SIL40C2 has a 0.6 to 5.0V DC 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 simplify 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.
