PRODUCT OVERVIEW

The MINMAX MKWI50 series is the latest generation of high performance dc-dc converter modules setting a new standard concerning power density. The

product offers fully 50W in an encapsulated, shielded metal package with dimensions of just 2.0”x1.0”x0.4”.All models provide ultra-wide 4:1 input voltage

range and precisely regulated output voltages.

A very high efficiency up to 92% which allows an operating temperature range of -40°C to +80°C is achieved by advanced circuit topology . Further features

include remote On/Off, trimmable output voltage, under-voltage shutdown as well as overload and over-temperature protection.

Typical applications for these converters are battery operated equipment, instrumentation, distributed power architectures in communication and industrial

electronics and many other space critical applications.

Specifications typical at Ta=+25℃, resistive load, nominal input voltage, rated output current unless otherwise noted.

Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.

Ripple & Noise measurement bandwidth is 20 MHz, measured with a 1μF MLCC and a 10μF Tantalum Capatitor.

All DC/DC converters should be externally fused at the front end for protection.

Other input and output voltage may be available, please contact factory.

To order the converter with heatsink, please add a

suffix -HS

(e.g. MKWI50-24S05-HS) to order code.

The MKWI50 series can meet EN61000-4-4 & EN61000-4-5 by adding a capacitor across the input pins.Suggested capacitor: CHEMI-CON KY 220μF/100V.

Do not exceed maximum power specification when adjusting output voltage.

Natural convection means an airflow of about 20LFM and is not equal to still air (0 LFM).

Specifications are subject to change without notice.
