Cxsu6305 series is a fixed frequency, high efficiency boost DC / DC controller, mainly used for OLED drive. The output voltage of the product can reach 22 V at most, and the OLED can be driven by 12V when the lithium battery is powered. A large tube with internal resistance of 2 ohm is integrated in the circuit, which can withstand 22V voltage. It adopts sot-23-5 small package to save PCB space and BOM cost
