Murata Power Solutions has introduced a series of isolated 30W DC/DC converters in a miniature 1/32 brick industry standard Distributed-power Open Standards Alliance (DOSA) compatible open frame package. The ULT measures 19.1 x 23.4 x 8.89mm and claims to take up significantly less board space than other 30W products on the market and is available with either through-hole or surface mount option, stated the company.

The ULT series has been designed with a wide (2:1) input voltage range of 36-75VDC to meet the requirements of 48V and 60V battery back-up systems. The initial product release includes 12Vout, 5Vout and 3.3Vout models. The maximum output power of 30W is available from the 12Vout model, with the 5V and 3.3V models producing 25W. Line regulation is typically within 0.1 percent of Vout across all Vin conditions at full load. An external trim function allows the output voltage to be trimmed by 10-20 percent to accommodate losses. Input to output isolation is certified to 1.5kV in accordance with the internationally recognized safety standard EN/UL60950.


The ULT series touts 30W max output power for the 12Vout model.

The ULT series offers remote On/Off control of either negative or positive logic, Vout trim and remote sense capability. In addition, the converter has protection features such as output short circuit protection, overtemperature shutdown and input undervoltage lockout.

The device was designed for a range of applications including distributed power architectures in industrial, telecommunications, routing, optical networking, wireless equipment and microwave radio/point to point communications.

The ULT series is designed to operate in the most severe outdoor environments with an operating ambient temperature range from -40C to 85C.
