DC/DC converters save space in 6.0, 8.0 and 10W applications

Taiwanese company, Minmax Technology has introduced the MD family of isolated DC/DC converter modules to Europe. They offer power density up to 63.5W/in3 for use in space-constrained designs, says the company.

The 6.0W MDWI06, 8.0W MDWI08 and 10W MDWI10 are available with 4:1 input voltage ranges of 9.0 to 36V or 18 to 75V. The MDW08 and MDW10 have a choice of three 2:1 input voltage ranges of 9.0 to 18V, 18 to 36V or 36 to 75V. All converters in the series are supplied in versions offering a fixed output voltage of 3.3V, 5V, 5.1V, 12V, 15V, 24V, ±12V or ±15V.

The MD converters are housed in a robust, encapsulated DIP16 package which has an industry-standard footprint of 0.94 x 0.54 x 0.31-inch (23.8 x 13.7 x 7.8mm).

The efficiency of the modules’ power regulation technology and thermal characteristics of the package design mean that the converters can achieve very high power density while supporting operation at temperatures up to 90 degrees C, says Minmax.

System design engineers can use an MD DC/DC converter to reduce both board footprint and weight typically by 50 per cent when replacing a competing module that has an equivalent power rating, claims Minmax.

The shielded metal case with insulated baseplate contribute to EMC performance. The MD products are certified for compliance with the EN 55032 EMI standard to Class A, and with the EN 61000-4-2/3/6/8 standard with no need for external components. Class A compliance with EN 61000-4-4/5 and with EN 55022 Class B require only a small number of external components.

Isolation of 1.5kV protects sensitive circuitry from noise, and supports use in safety-critical applications. Typical peak efficiency is 88 per cent at the maximum load, and no-load power consumption is just 0.1W. Line regulation is rated at ±0.2 per cent, and load regulation is rated at ±0.5 per cent.

The converters have no minimum load requirement, and maintain stable regulation with no oscillation in no- and light-load conditions. Typical start-up time of 20ms helps eliminate the risk of system timing failures.

All MD family parts are now available in production volumes to customers throughout Europe via local channel partners, or globally from Future Electronics.
