DC-DC Converters and Current Control Modules Have High Power and Efficiency

All of Vishay Intertechnology Inc.’s FunctionPAK dc-dc converters and current control modules are available in a new surface-mount adaptor board configuration to support engineering prototype assembly. While most production operations can handle the standard FunctionPAK surface-mount BGA configuration, the new "SM" versions of the FunctionPAK devices will facilitate the assembly process for any engineering lab that finds it difficult to handle the BGA configuration in its prototype assembly lab. The "SM" versions are the second of two FunctionPAK options expressly intended to streamline the design prototype process.

Vishay FunctionPAK dc-to-dc converters require no external components to achieve the complete circuit function. Intended primarily for point-of-load (POL) converters in intermediate bus architectures, these converters are available as either boost or buck converters with power output up to 15 W and output current up to 4 A. Input voltages from 2.5 V to 6 V are converted to output voltages of 0.8 V to 6 V, with efficiencies up to 95%. Vishay current control products, also available in the surface-mount adaptor board configuration, include a 15-W, 2.5-A power LED driver and a smaller 60-W, 2-A (max.) current controller. The controller is available with a single channel or with two channels (one or two independent controllers) in the same package.

Although intended primarily for prototyping operations, FunctionPAK "SM" versions also are available in production quantities. Both samples and production quantities are available now, with lead times of six weeks for larger orders. Pricing for U.S. delivery in 50-piece quantities starts at $13.53.
