Provides optimized cost and performance ratioPromising designers a cost effective yet high performance solution, the new PKM4000D series of DC/DC converters from Ericsson Power Modules is designed to provide an optimized cost and performance ratio for today and tomorrow's applications.

As part of the company's third generation of DC/DC power modules, the PKM-D family offers one of the best alternative to cost reduction programs when using quarter bricks up to 40A. The first two productsPKM4110D and PKM4119D, are rated at 3.3V at 35A and 2.5V at 40A, respectively. This family will also embrace converters with voltage outputs of 1.2-, 1.5-, 1.8-, 5- and 12V.

According to the press release, the fully DfE and RoHS compliant converters offer high efficiency figures due to the use of a unique patented synchronous rectification technique developed by Ericsson Power Modules' for use in its higher power series of converters to achieve outstanding efficiency at high currents and low voltages. This technique provides a low component count and thus provides greater reliability at lower cost, added Ericsson Power Modules.

Featuring an input voltage range of 36V to 75V, the PKM-D platform uses an integrated magnets design to achieve its compact, quarter brick format. All models in the family offer current limit, overvoltage, and over temperature protection. Other features include remote sensing, output voltage adjust (Vadj) and remote control.
