Murata releases two DC/DC converter ranges

Murata Power Solutions has added two ranges of single output, half-brick isolated DC/DC converters to its product portfolio.

The HPH series are ultra-high output converters with different models capable of delivering up to 360W of power and 70A output current.

The UCH series comprises modules that deliver between 50W and 150W of output power and a maximum output current of 40A.

The HPH and UCH series are isolated to 2250VDC with an open-frame construction and are designed for PCB mounting.

Both series are in compliance with RoHS legislation and have UL60950-1 and EN60950-1 safety approvals.

HPH DC/DC Converters offer regulated single outputs ranging from 3.3VDC to 12VDC.

An input voltage range of 36VDC to 75VDC, combined with an industry standard pinout and package measuring 61 x 58.4 x 10.2mm simplifies the use of the modules in low voltage/high current OEM applications.

The new converters utilise a full-bridge, fixed-frequency topology along with synchronous output rectification that enables levels of efficiency of up to 91 per cent.

Operating temperature range is -40C to +85C.

The UCH series has outputs from 2.5VDC to 15VDC and a choice of either 36VDC to 75VDC or 18VDC to 36VDC input voltages.

Module footprint and installed height are identical to the HPH series.

UCH series DC/DC Converters are ideal for demanding telecom, datacom and networking applications and their semi-synchronous rectifier design helps them achieve efficiency levels of up to 92 per cent.

The standard operating temperature range for the UCH family is -40C to +85C.

By using an optional baseplate, the thermal perrformance can be further improved.

Remote sense, output trim and primary side on/off control with either positive or negative logic are included in the design of both new product series.

Both series provide short circuit protection and thermal shutdown, plus input under-voltage and input/output over-vo.
