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″ (23.8mm x 13.7mm 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 to 36V or 18V to 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.
