Bel Power Releases Point-of-Load Power Converters Featuring Tunable Loop™ Technology

ELECTRONICS: Bel Power, a division of Bel Fuse Inc. announced the addition of the SLIN Series of non-isolated, point-of-load (POL) dc/dc converters to their growing portfolio of parts targeting distributed power architectures and intermediate bus voltage applications. Under the terms of a licensing agreement with Lineage Power Corporation, Bel’s new SLIN Series features Tunable Loop™ technology, which allows engineers to optimize the dynamic response of the converter to match customers’ specific load requirements. This minimizes the quantity, type and size of the capacitors needed for any given application, and offers significant cost and performance advantages over other solutions and technologies. Packaged in a standard Distributed-power Open Standards Alliance (DOSA) footprint, and available in 3A, 6A, 12A and 20A versions, the SMT modules offer OEMs/ODMs maximum flexibility and efficiency without compromising development schedules. The SLIN Series is engineered to operate over a wide input voltage range of 4.5 to 14V and provide a precise output voltage of 0.59 to 5.5V, programmable via an external resistor. The series moreover consists of modules, which operate at efficiencies of up to 94.3 percent. Parts are RoHS EU Directive 2002/95/EC complaint, and carry a full set of international safety approvals including UL and UL60950.

The cost-effective, compact, open-frame construction of the SLIN Series makes these converters ideally suited for an array of state-of-the-industry, high-current microchip designs requiring dense inter-board spacing. Parts are used in a variety of applications, ranging from simple standalone operation to an integrated component of sophisticated power architecture. They are most commonly specified for use on PC boards in telecommunications equipment, server and storage applications, and enterprise networks.

The new power modules’ features include tight 10-millivolt load voltage regulation, fixed frequency synchronous rectification control, remote on/off, adjustable output voltage, over-current and over-temperature protection, output voltage sequencing, and paralleling with active current sharing. They additionally provide a power good signal and current sink/source capabilities. Parts operate over an ambient temperature of -40 to +85C.

Pricing for the SLIN Series, in quantities of 10,000, is $4.60, $4.80, $5.45 and $6.05 each for the 3A, 6A, 12A, and 20A models, respectively.  Samples and production quantities are available from stock with lead times of up to 12 weeks.
