RP20-4812SA-HC

DC DC Converters are electronic circuit devices used to convert one form of electric power to another. A common example is the conversion of AC electricity into DC electricity for use in electronic circuits. One type of such device is the RP20-4812SA-HC. This article will focus on the application field and working principle of this device.

Application Field

The RP20-4812SA-HC is a constant voltage-current source. It is a high-frequency pulse-width modulation DC-DC converter module with a wide input voltage range from 4.5V to 35V and with an adjustable standard type output voltage of 4.8V-12V. It is mainly used in LCD/LED displays, computers, DC motors, DVD players, communication systems and other electronic equipment.

Working Principle

The working principle of the RP20-4812SA-HC is based on the concept of pulse-width modulation, or PWM. It is an effective way to regulate energy transfer between two circuits. In this case, the PWM controls the current supplied to the output circuit. When the PWM duty cycle is increased, more current flows to the output. When the PWM duty cycle is decreased, less current flows to the output.

The output voltage is controlled by the adjustment of the internal control circuits and the pulse-width modulation duty cycle. The output current is regulated by adjusting the duty cycle of the internal pulse-width modulator and by monitoring the output current envelope. This ensures that the output current only reaches the desired set point.

The RP20-4812SA-HC features low harmonic distortion and a wide operating temperature range of -30 to +85C for reliable performance in any condition. It also has various protections such as overvoltage protection, overcurrent protection, and short-circuit protection. With its high efficiency and low noise operation, this DC-DC converter module is ideal for a wide range of applications.

Conclusion

The RP20-4812SA-HC is a high-frequency pulse-width modulation DC-DC converter module that is used in a wide range of applications due to its high efficiency, low noise operation, and multiple protections. It works by adjusting the pulse-width modulation duty cycle to regulate energy transfer and to adjust the output voltage and current. This device is a highly reliable choice for any application.
