DC-DC Converters

DC-DC converters can be used to convert power from one level of direct current (DC) to another level of direct current. It can be used to step up, step down and even convert between alternating current and direct current. REM10-053.3S/A/CTRL is an example of a DC-DC converter. In this article, the application fields and working principle of REM10-053.3S/A/CTRL will be discussed.

Application Fields

REM10-053.3S/A/CTRL is a DC-DC converter designed specifically for telecom applications. It is a rugged device and is reliable even in harsh environments since it is encapsulated using a specialized glueless construction. It has extreme temperature range from -55 degree Celsius to +85 degree Celsius and strict EMC approvals. The device has high efficiency and low no load input current which makes it perfect for many telecom applications.REM10-053.3S/A/CTRL has output voltages ranging from 3.3V to 5., output powers up to 15 watts, operating frequencies ranging from 100 kHz to 200 kHz, high step up and step down ratios of up to 25 and low ripple. All these features make it perfect for telecom system power supply.

Working Principle

REM10-053.3S/A/CTRL uses the principle of pulse width modulation to generate a steady output voltage at its output pins. The converter is integrated with a control circuit, which constantly senses the output voltage. If the output voltage is low, the control circuit will increase the duty cycle of the pulse width modulation, thus increasing the output voltage. If the output voltage is too high, the control circuit will decrease the duty cycle to regulate the output voltage. The output voltage can also be remotely set using on-board potentiometer.The converter utilizes a high frequency switching topology. It consists of a high frequency step-down chopper, active clamp, and a low frequency step-down chopper. The high frequency step-down chopper is used to regulate the turn-on time of the low frequency step-down chopper and reduce the conduction loss. The active clamp is used to reduce the voltage spikes, thus reducing the EMI. The low frequency step-down chopper is used to transform the high voltage AC to the desired output voltage. The converter is also integrated with a timeout protection circuit, which will shut off the output voltage when the converter is working in an abnormal mode. It is also integrated with a short circuit protection circuit to protect the converter from damage.

Conclusion

REM10-053.3S/A/CTRL is a high performance DC-DC converter, which is specifically designed for telecom applications. Its high efficiency, low noise, and robust construction make it perfect for telecom system power supply. It applies the principle of pulse width modulation to regulate the output voltage. The converter is integrated with a control circuit, an active clamp, a short circuit protection circuit, and a timeout protection circuit to ensure safety and reliability.
