Available as through-hole mounting with staggered style pinouts, the MEU1 achieves a 25% increase in power density and can deliver its output power over the whole temperature range of – 40 degrees C to +85 degrees C.
Conversion efficiency has also been improved by typically 6% across the full load range compared to previous models. Efficiency improvements contribute to lowering the overall system power consumption in addition to increasing system reliability.
The MEU1 series also has load regulation that is typically 3% better than the industry norm when compared to similar miniature through-hole converters. This reduces the need for any additional external regulation components and further conserves precious board space.
A total of 14 models are available across the series, catering for the popular input voltages of 3.3, 5, or 12 VDC and providing outputs of 3.3, 5, 9, 12, or 15 VDC. 1kVDC galvanic isolation aids reduction of switching noise and allows the converter to be configured to provide an isolated negative rail in systems where only positive rails exist.
Ann-Marie Bayliss, Product Marketing Manager, Murata, comments, “The MEU1 sets a new industry footprint standard for 1W DC-DC converters. Engineers wishing to reduce the size of their end-products are always looking at ways to conserve board space. The MEU1 helps them achieve this while still providing excellent efficiency and load regulation characteristics.”
Certification to the international safety standard UL/IEC 60950 is pending.
