4:1 Input 3W SIP Regulated and Isolated DC-DC

Murata announces the NCS3 series of isolated 3-Watt dc-dc converters manufactured by Murata Power Solutions. These through-hole mounting converters are packaged in an industry standard, pin compatible, SIP format, making them suitable as a replacement part when updating older product designs. Accommodating a wide 4:1 input voltage range around either a 12 Vdc or 48 Vdc nominal, the NCS3 series comprises eight single-output regulated models providing a choice of 3.3-, 5-, 12-, or 15-Vdc output.

The wide input voltage suits applications where the nominal input voltage might be different, or where wide voltage deviations are anticipated. Output regulation is quoted as better than 1% of stated output, meaning that no additional voltage regulation components are required, saving both cost and valuable board space. Input / output isolation of 1,500 Vdc is standard across the range.

The NCS3 can deliver 3 watts across a wide range of operating temperatures from -40 to +95 degrees C with model-dependent derating. Safety features include continuous output short circuit protection and certification to the internationally recognized UL60950 safety standard.

Ann-Marie Bayliss, product marketing manager, Murata Power Solutions comments, “With the launch of the NCS3 we continue to build on our range of wide input dc-dc converters and can now offer products at 1, 3, 6, and 12 Watts output.”

Compared to similar products available, the NCS3 series offers up to a 3% power conversion efficiency improvement that aids in lowering overall system power consumption in addition to enhancing product and system reliability.
