Minmax — Isolated 8W DC/DC Converter with Wide 4:1 Input Range in Small DIP Package

MINMAX’s new MDWI08 series of 8W isolated DC/DC converters, housed in a 16-pin DIP package measuring just 0.94” x 0.54” x 0.31” (23.8 x 13.7 x 8.0mm), offers a very high power density of up to 50W/in3. The shielded metal package has a built-in EMI filter.

The MDWI08 series consists of 14 models which operate over wide input-voltage ranges of 9V – 36V or 18V – 75V. Single-output models are available with fixed outputs of 3.3V, 5V, 12V, 15V or 24V, or dual outputs of ±12V or ±15V.

Typical efficiency when supplying the maximum 8W load is up to 86%.

The converters operate over an ambient temperature range of -40°C to +80°C. The converters’ output is derated at over +70°C with no forced air cooling required.

The MDWI08 converters offer precise regulation of the outputs: line regulation is accurate to a maximum ±0.8%, and load regulation to ±1.0%.

The MDWI08 has no minimum load requirement, and no-load power consumption is very low: the 9V – 36V models draw just 3.1mA at no load, and the 18V – 75V parts draw 2.1mA.
