The MEU1 series of ultra miniature single isolated output 1 Watt DC-DC converters measure just 8.30 x 6.10 x 7.55 mm, achieving a 26% footprint reduction when compared to previously released products. 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 -40oC to +85oC. The reduction in converter volume and footprint allows engineers to reduce the overall dimensions of their application, which is critical for space-constrained designs.

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.
