MJWI20-24S12: A New-Generation and High-Performance DC-to-DC Converter

MJWI20-24S12 is a DC-to-DC converter by MINMAX. The company has been manufacturing this type of converters for over 30 years, so you can rely on the performance and quality of the MJWI20-24S12.

Commitment to Quality Service Delivery

MINMAX has been committed to offering customers value for their money. The manufacturer thrives on the need to offer products that have the best power density characteristics, as well as reducing the sizes of these products.

Thus, you can be sure of getting a combo of size miniaturization and high-power density from the MJWI20-24S12 DC-to-DC converter.

How Does the Converter Work?

MJWI20-24S12 is a DC-to-DC converter designed to offer the highest levels of performances, while making power and signal transmission flexible.

For that purpose, the converter has optimized the converter modules to help set the standards for the highest power densities.

High Efficiency

MJWI20-24S12 also offers one of the best efficiencies, in terms of operation. This is offered first via the circuit topology that enables the converter to attain up to 85% efficiency. In addition to this, it improves the temperature range from a minimum of -40˚C to a maximum of +85˚C.

Understandably, a DC-to-DC converter, and indeed, any consumer electronics’ integral component, needs to be regulated. For that reason, this converter has been equipped with the ultra-wide 4:1 input voltage range. This allows for the input and the output voltages to be under “tight” regulation.

Converter Protection

MJWI20-24S12 is also shielded from some potential dangers. For example, it uses the combined functions of overvoltage and the undervoltage protection to regulate the converter when the voltage goes below or above the predefined values.

There is also the short-circuit protection in place to prevent the converter from bypassing current or voltage while in use.

One other safety measure for MJWI20-24S12’s use is the compliance with the safety approval requirements, as enshrined in the UL/cUL/EC/EN 62368-1(60950-1). The MJWI20-24S12 DC-to-DC converter also has the CB Marking and the CB Report.

Compact Design

MJWI20-24S12 doesn’t take up much space, just like most of the other (converters) by MINMAX.

The small form-factor design includes an ultra-compact 1-inch x 1-inch package and one of the smallest encapsulated 20-Watt converters shielded in a metal package.

Information about the MINMAX Range of DC-to-DC Converters

There are several converters manufactured by MINMAX, but the DC-to-DC converters stand out the most. Aside from the aforementioned properties of MJWI20-24S12, there are many other features yet-to-be talked about.

These are some of the additional details of the DC-to-DC converters manufactured by MINMAX:

1. Strict Regulatory Compliance

One of the banes of working with a DC-to-DC converter is the uncertainty surrounding the compliance. You want to be sure that it is compliant with the existing rules.

In the case of MINMAX, the company makes sure that the variety of DC-to-DC converters it produces meet the requirements of the IEC/EN/UL62368-1 international safety regulations. It also has mechanisms in place to ensure the compliance of these converters with the existing EU CE electromagnetic compatibility regulations.

Making sure that these converters comply with the aforementioned regulatory policies is the basic step. MINMAX has also went on to set-up an electromagnetic wave verification laboratory. The laboratory complies with the IEC International Standards.

One of the highpoints of the laboratory’s contribution is the certainty that the converters are not in proximity or in close contact with the surface or body of the other electronic components when in use.

2. MINMAX Makes DC-to-DC Converters for a Wide Range of Applications

This manufacturer makes all converters to fit into specific applications. From the industrial to railway, medical and ultra-high isolation applications; these DC-to-DC converters meet all the requirements.
