PRODUCT OVERVIEW NCM6D0505C 20 1500 20
NCM6D0512C 25 1450 20
The NCM6 series of DC-DC converters offers
NCM6D0515C 30 1450 15
single & dual output voltages from wide input
NCM6S0503C 8 1300 10
voltage ranges of 4.5-9, 9-36V & 18-75V.. The
NCM6S0505C 20 1500 20
NCM6 is housed in an industry standard package
NCM6S0512C 25 1500 90
with a standard pinout. The NCM6 is encapsulated
NCM6S0515C 30 1500 90
for superior thermal performance.
