A dual input output DC-DC converter is a power conversion device that can receive inputs from two different power sources and output a stable DC voltage. It is usually used in application scenarios that require flexible power management and high-efficiency conversion, such as hybrid systems powered by solar and batteries, automotive electronic equipment, and certain industrial equipment. The following is a detailed introduction to this type of device.
Working Principle of Dual Output DC Converter
A dual input output DC converter can receive voltages from two different sources at the same time and select the appropriate input for voltage conversion according to the load requirements. Its basic working principle mainly includes the following steps:
Input selection: The converter uses switching elements (such as MOSFETs) or relays to select and activate one of the input sources to ensure stable power supply to the system. This selection can be manual or automatically performed by the control circuit, switching according to voltage levels, load requirements, or fault protection strategies.
Voltage conversion: After the input source is selected, the converter will adjust the output voltage in real time through the internal inductor, power switch, and control circuit to ensure that the DC voltage provided to the load meets the predetermined requirements.
Output rectification and filtering: The converted voltage usually passes through rectification and filtering circuits to ensure the stability and low ripple of the output voltage, which is suitable for the needs of sensitive electronic equipment.

It is mainly a voltage converter that can effectively output a fixed voltage after converting the input voltage. It is mainly divided into three types: boost type, buck-boost type, and buck type, and three control methods can be used according to needs. The PWM control method is highly efficient, and the output voltage ripple and noise are good; the advantage of the PFM control method is that even if it is used for a long time, especially under light load, the power consumption is very small. When the PWM/PFM conversion is small load, PFM control is used, and it automatically converts to PWM control when the load is large. At present, DC-DC converters are widely used in mobile phones, MP3, digital cameras, portable media players and other products. In the circuit type classification, it belongs to the chopper circuit.
