Encapsulated DC-DCs with 4:1 Input meets Medical Safety Standard
Murata today announced the NCM6 series of isolated 6-Watt single- and dual-output dc-dc converters from Murata Power Solutions. Accommodating up to an ultra-wide 4:1 input range, these dc-dc converters are available in three nominal input voltage ranges of either 5-Vdc input (4.5- to 9-Vdc, 2:1 range), 12-Vdc (9- to 36-Vdc, 4:1 range) or 48-Vdc (18- to 75-Vdc, 4:1 range). Each nominal input voltage variant offers seven output voltage models.
Four of these are single-output versions with +3.3-, +5-, +12- or +15-Vdc output. Three dual-output models provide +5-, +12- or +15-Vdc output options. Recognition of certification to international safety standards UL60950 for IT equipment and 3rd edition medical safety standard UL60601 for 2 MOOP is pending. The dc-dc converters are encapsulated in order to achieve high levels of thermal performance and are housed in an industry standard package measuring 20.0 x 32.0 x 10.75 mm.
The operating temperature range is from – 40 to +85 degrees C and the device is protected against damage due to excess operating temperatures. An input undervoltage lockout feature protects the output should the input voltage fall below specified limits. Input to output isolation is 5200Vdc.
