Description
technical field [0001] The invention relates to a DC voltage conversion circuit. Background technique [0002] At present, the conversion technology of DC voltage is relatively mature. The traditional DC voltage conversion technology generally can only achieve unidirectional conversion of the power supply, such as Figure 1a The circuit shown is a typical step-down circuit (buck converter), which can convert a 5V input voltage into a 3.3V output voltage required by the system, but this step-down circuit cannot reverse the 3.3V output voltage Transformed into 5V voltage and output from the input terminal. If you want to achieve this reverse conversion, you need to use another boost circuit (boost converter, see Figure 1b )). Figure 1a The circuit 10 in is a traditional step-down conversion circuit, and the step-down control module 11 monitors the output voltage (Vout), thereby stepping down the input voltage (Vin) to a set output voltage (Vout). Figure 1b The circuit 13...
