Murata New 4:1 input 3W SIP regulated and isolated DC-DC converter

24-09-2015 | Murata | Power

Murata Power Solutions has introduced the NCS3 series of isolated 3W DC-DC converters. The through-hole mounting converters are packaged in an industry-standard, pin-compatible, SIP format, making them ideal as a replacement part when updating older product designs. Accommodating a wide 4:1 input voltage range around either a 12VDC or 48VDC nominal, the NCS3 series comprises eight single-output regulated models providing a choice of 3.3, 5, 12 or 15VDC 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 1,500VDC is standard across the range. The NCS3 can deliver 3W across a wide range of operating temperatures from -40C to +95C 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, said: “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 12W output.” Compared to similar products available the NCS3 series offers up to a 3% power conversion efficiency improvement that aids lowering overall system power consumption in addition to enhancing product and system reliability, says the company.
