40A DC/DC converter achieves over 90% efficiency level

Smyrna, Ga.—Murata Power Solutions' UCE series of eighth-brick DC/DC converters is available with fixed output voltages from 1.5V to 12V, output current to 40A and output power up to 100W.

The UCE series of fully isolated DC/DC converters have a high-density, open-frame design that uses an interleaved synchronous rectifier topology to achieve efficiency levels of more than 90%. The modules accept a wide input voltage range of 36VDC to 75VDC, with high thermal performance and derating enabling them to operate with full-rated power at their maximum 85°C operating temperature with only moderate airflow. Minimum operating temperature is -40°C.

Compact overall dimensions of 58.4-mm x 22.9-mm and a low profile of just 10.16mm allow the UCE series to be incorporated in designs where space is limited. Typical applications include distributed power architectures, servers, plus telecoms, wireless and information technology equipment.

UCE series DC/DC converters are RoHS compliant and fully protected against input over/undervoltage, output overcurrent and short-circuit. An on-board temperature sensor shuts down the converter if thermal limits are reached; output protection automatically restarts the converter when the fault is removed.

A remote on/off control input enables phased start-up and shutdown in multi-voltage applications, as well as standby operation which provides power savings. Output trim and sense functions are also provided.

The UCE series has UL/EN/IEC 60950 safety approvals and has been subjected to EMI testing performed to widely accepted EMC standards.

Pricing: Starts at $35 in OEM quantities.
Availability: Lead-times from stock to 12 weeks ARO.
