V7809-500 Working Principle

The V7809-500 DC/DC converter is designed to work on the principle of PWM switching. This means that when the input voltage is higher than the output voltage, the converter will switch between two voltages, the higher source voltage and the lower load voltage, at a specified frequency. This switching causes the output voltage to be lowered to the desired level. The alternating high and low voltage pulses are then smoothed out by an integrated low pass filter to create the steady output voltage.

This technique is highly efficient, and ensures that the voltage ripple is kept to a minimum. However, it is important to ensure that the input voltage is adjusted to the correct level, in order to maintain the correct input-output regulation. Over-voltaging may cause the converter to overload, which will reduce the efficiency and eventually lead to the failure of the converter.

Conclusion

The V7809-500 DC/DC converter is a highly efficient, wide input to low output voltage, stepped down DC to DC power converter. Its3V-17V input voltage range, high efficiency, low output voltage ripple, high switching frequency, and compact size make it ideal for applications such as LCD displays, LED backlighting, and low-voltage circuit designs. Additionally, it works using the principle of PWM switching, which helps to maintain its efficiency while providing a steady output voltage.
