 DC/DC refers to a device that converts a DC power supply of a certain voltage level into a DC power supply of another voltage level. DC/DC is divided into two types according to the voltage level transformation relationship: boost power supply and buck power supply, and isolated power supply and non isolated power supply according to the input output relationship. For example, in mobile phone application circuits, it is often necessary to drive the LED of the flash module or the LED of the display backlight through a boost circuit, and it is usually possible to adjust the brightness of the LED according to the needs of different situations.

 DC/DC refers to a device that converts a DC power supply of a certain voltage level into a DC power supply of another voltage level. DC/DC is divided into two types according to the voltage level transformation relationship: boost power supply and buck power supply, and isolated power supply and non isolated power supply according to the input output relationship. For example, the power supply for security monitoring generally uses PoE or DC 12V DC power supply, which is reduced to 5V or 3.3V through the first level DCDC converter, and then reduced to provide power for DSP, DDR, and PHY through the second level DCDC converter.

The core advantage of the buck boost DC-DC controller is that it can provide stable output regardless of whether the input voltage is higher, lower, or equal to the output voltage. Modern solutions often adopt a four switch single inductor topology, which supports seamless switching between buck, boost, and buck boost modes, with an efficiency of over 95%. It also integrates protection functions such as overcurrent and overheating, making it an ideal choice to solve the contradiction between wide voltage input and stable output.
