DC DC Converters

DC-DC converters are devices that can convert a DC voltage from one level to another–either higher or lower. There are a variety of models available, each with different functions and features. One of the most widely used models is the REC3-0515DR/H1 Converter. This DC-DC converter offers a range of features and benefits.

The REC3-0515DR/H1 DC-DC Converter

• Single Input Voltage (±15V Nominal)
• Isolated Output Voltage (2.5 to 5V), Adjustable
• Output Current up to 5.3A
• Operating Temperature Range: -40°C to +85°C
• Low Ripple and Noise (Max 20mVp-p)
• Built-in Internal Heatsink

The REC3-0515DR/H1 Converter is a power supply module offering an isolated output voltage of 2.5V to 5V. Its output current is up to 5.3A, making it ideal for applications requiring large amounts of power. In addition, the converter has a built-in internal heatsink for better heat dissipation, and its ripple and noise is kept at a low maximum of 20mVp-p.

The Working Principle of the REC3-0515DR/H1 Converter

The REC3-0515DR/H1 Converter utilizes a two-stage DC to DC conversion process for its operation. In the first stage, it uses buck-boost topology to step down the input voltage from the±15V nominal to a predefined regulated voltage as the intermediate voltage. This is done using a switching regulator based on the voltage regulation feedback loop. In the second stage, the intermediate voltage is further stepped down to the desired output voltage, using the same buck-boost topology. This is done using a PWM (Pulse-Width Modulation) controller IC, which adjusts the duty cycle of the switching regulator to produce the desired output voltage.

Applications of the REC3-0515DR/H1 Converter

The REC3-0515DR/H1 converter is suitable for a wide range of applications, such as industrial, medical, telecom, and automotive. It is ideal for applications requiring a large output current. For instance, it can be used for motor control, HVAC systems, LED lighting, medical equipment, etc. In addition, it can be used in high voltage applications, as it has the ability to convert a wide input voltage range of±15V to achieve the desired output voltage.

Conclusion

In conclusion, the REC3-0515DR/H1 Converter is an ideal choice for applications requiring a wide range of output voltage and large output current. The converter utilizes a two-stage DC to DC conversion process for its operation which makes it a reliable and efficient choice. It is suitable for a wide range of applications such as automotive, industrial, telecom, and medical.
