Murata has announced the MEU1 series of ultra miniature single isolated output 1 Watt DC-DC converters. Measuring 8.30 x 6.10 x 7.55 mm, this new series achieves a 26% footprint reduction when compared to previously released products.

Available as through-hole mounting with staggered style pin outs, 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.

"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 company said.

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, with 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.

Certification to the international safety standard UL/IEC 60950 is pending.

With lead-time from stock to 10 weeks, pricing in OEM quantities is in the range of Rs.188.68 ($3.00).
