100W dc/dc converter for power radio applications
Ericsson Power Modules' PKM4116ND quarter brick dc/dc converter has been optimised to lower the number of components and reduce power losses. The product is said to be pin to pin compatible with similar products available and has been designed to enable systems designers to shorten time to market.
The converter has been designed for the new generation of micro cell transmitters requiring a 100W power module, with the flexibility to adjust its output voltage between 23.8 to 32.8V. The main application area is in radio frequency power amplifiers and other applications requiring isolation from the 48V system bus voltage. The product is also said to be suitable for small systems remote feeding power architectures such as indoor wifi transmitters.
The layout has been optimised to distribute the major heat dissipating components, eliminating hot spots and improving cooling through natural thermal conduction from board to cold plate.
