DC-DC converters cost-optimised for wireless/microwave applications

Flex Power Modules has introduced the PKU4611A and PKU4617A, two new isolated DC-DC converters in the sixteenth-brick form factor. The new converters are perfect for low-power RFPA needs within small cell radios and microwave applications. They provide a wide output trim range, which is optimised for the needs of low-power radio designs that need a 5V to 7V supply. The converters’ offer excellent efficiency, at typically 94% at half load and 5V output voltage. With an input voltage range of 36V to 60V, both versions offer up to 60W output power: the PKU4611A at up to 5V/12A and the PKU4617A at up to 6V/10A. Olle Hellgren, director of product management and business development at Flex Power Modules, said: “With these new converters, Flex Power Modules has focused our attention on optimizing cost wherever possible – delivering a cost-efficient solution, without any compromise on quality, thermal performance or reliability.”
