Murata has announced the NCS3 series of isolated 3 watt DC DC converters. These 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 3 watts across a wide range of operating temperatures from -40˚C to +95˚C with model-dependent derating.
Safety features include continuous output short circuit protection and certification to the internationally recognised UL60950 safety standard.
Compared with 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.
