HPH series DC/DC converters

Murata has released two ranges of single output, half-brick, isolated DC/DC converters.

The HPH series is a family of ultra-high output converters with different models capable of delivering up to 360 W of power and 70 A output current. The UCH series comprises modules that deliver between 50 and 150 W of output power and a maximum output of 40 A.

Both series are isolated to 2250 VDC 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.

The converters offer a choice of fully regulated single outputs ranging from 3.3 to 12 VDC. A wide input voltage range of 36 to 75 VDC, combined with a standard pinout and package measuring 61 x 58.4 x 10.2 mm, simplifies the use of the modules in low-voltage/high-current OEM applications.

The converters use a full-bridge, fixed-frequency topology along with synchronous output rectification that enables levels of efficiency up to 91% to be achieved.

The UCH series is available with outputs from 2.5 to 15 VDC and a choice of either 36 to 75 or 18 to 36 VDC input voltages. Module footprint and installed height are identical to the HPH series.

The UCH series is suitable for telecom, datacom and networking applications with its semi-synchronous rectifier design helping achieve efficiency up to 92%.
