1/32-brick DC-DC converters

2 May 2012 Power Electronics / Power Management

The ULT series of isolated 30 Watt DC-DC converters is available from Murata in the miniature 1/32-brick industry standard. The Distributed-power Open Standards Alliance (DOSA) compatible open-frame package, measuring just 19,1 x 23,4 x 8,89 mm, is available in through-hole and surface-mount variants.

The devices have been designed with a wide (2:1) input voltage range of 36–75 V d.c. to meet the requirements of 48 V and 60 V battery backup systems. They are available with outputs of 12 V, 5 V or 3,3 V. The maximum output power of 30 W is available from the 12 V model, with the 5 V and 3,3 V models producing 25 W.

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 1500 V in accordance with the internationally recognised safety standard EN/UL60950.

The ULT series offers features that include remote on/off control of either negative or positive logic, Vout trim and remote sense. It also has a number of protection features including output short circuit protection, over-temperature shutdown and input under-voltage lockout.

Target applications include 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 -40°C to +85°C.
