DC DC Converters

A DC DC Converter is a small electronic device that converts direct current (DC) electricity from one voltage to another, usually between 5 and 24 volts. It is often used in power supplies for electronic devices and can be found in many consumer electronic products. The MEZD71203A-B is a DC/DC Converter designed for applications requiring high power density with fast conversion time and reliable operation. This article examines the application field and working principle of the MEZD71203A-B.

Application Field

The MEZD71203A-B is designed primarily for applications requiring high power density such as servers, workstations, and storage systems. It is also suitable for applications such as communications systems, radar, navigation, automotive, and medical systems.

This device is approved for use in equipment up to 60 VDC input and can be used in Class II Divisions 1 & 2 hazardous locations and is UL certified in sizes from 0.3” to 0.71”. It is also industrial rated for operations temperatures of -40°C to +105°C.

Features & Benefits

The MEZD71203A-B features a high-power density of 45W/in3, a wide temperature operating range of -40°C to +105°C, and a wide input voltage range of 4.5V to 60V. This device also features an input under-voltage lockout (UVLO) function, cycle-by-cycle current limit protection, overload protection, and short circuit protection.

The benefits of using this DC/DC converter are the high power density, efficient operation, wide operating temperature range, high operating frequency, and low EMI (electromagnetic interference). This device also has good thermal efficiency, with no load power consumption as low as 250mW for the 2W version. Additionally, it is shorter and lighter than traditional converters, and is RoHS Compliant.

Working Principle

The MEZD71203A-B is a buck (step-down) converter which works by taking in a direct current (DC) input voltage and converting it to a lower direct current (DC) output voltage. The input voltage is typically higher than the desired output voltage. The device then uses a switch to short the voltage while cutting off the current, followed by a filter which removes the high-frequency components in the output, thus providing a steady output voltage.

The device contains an inductor and a capacitor to provide the necessary filtering of the output. The inductor stores energy when the switch is closed and releases energy when the switch is opened. The capacitor provides the necessary filtering of the output. The output voltage is then regulated to a certain level by a feedback circuit which compares the output voltage to a reference voltage.

Conclusion

The MEZD71203A-B is a reliable and efficient DC/DC converter designed for applications requiring high power density with fast conversion time. It is suitable for servers, workstations, storage systems, communications systems, radar, navigation, automotive, and medical systems. It features a wide temperature operating range, wide input voltage range, and robust protection functions. It also boasts high efficiency, low EMI, low no load power consumption, and RoHS compliance. Its working principle involves taking in a direct current input voltage and converting it to a lower direct current output voltage.
