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 -40C to +85C. Conversion efficiency has also been improved by typically 6% across the full load range compared to previous models. 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.
A total of 14 models is 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. 1-kVDC 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. Certification to the international safety standard UL/IEC 60950 is pending.
