DC/DC converter suits wireless backhaul applications

With a fixed 12VDC/20A single output, the DOSA compatible, open-frame quarter brick package occupies only 58.4 x 36.8 x 11.7mm. The converter accepts a wide 3:1 input range of voltage from 18 to 60VDC around a nominal 48VDC. A remote sense feature provides the automatic adjustment of Vout to make up for line and load losses, while a trim function allows +/-10% of Vout. The series has tight load and line regulation that ensures that the output voltage does not vary beyond +/-1.25% when the load changes. The UWQ-12/20-T48 has a typical efficiency of 92% and up to three units can operate in parallel in order to provide redundancy or load sharing of a higher power requirement. Controls include remote On/Off control of either negative or positive logic. In addition, the converter has a number of protection features including overcurrent, overtemperature, input undervoltage and output short circuit.
