Murata – Industry’s first DOSA compliant 1/32 brick 30W DC-DC converters (Murata ULT series)

Murata PS Solutions has announced the ULT series of isolated 30W DC-DC converters available in a miniature 1/32 brick industry standard Distributed-power Open Systems Alliance (DOSA) compatible open-frame package. Measuring just 19.1mm x 23.4mm x 8.89mm, the ULT series takes up significantly less board space than other 30W products on the market and is available with either through-hole or surface mount option, says the company.

The ULT series was 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 with lower voltages to come in the near future. 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% of Vout across all Vin conditions at full load. An external trim function allows the output voltage to be trimmed by + 10 % to – 20% to accommodate losses. Input to output isolation is certified to 1,500V in accordance with the internationally recognized safety standard EN/UL60950.

The ULT series offers features that include remote On/Off control of either negative or positive logic, Vout trim and a remote sense capability. In addition the converter has a number of protection features including output short circuit protection, over temperature shutdown and input under voltage lockout.

The ULT series was designed for a wide range of applications including distributed power architectures in industrial, telecommunications, routing, optical networking, ireless 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, says the company.
