This manual describes the XLSEMI XL4015 demo board, a buck converter supporting 8V to 36V input and 5V/5A output with up to 93% efficiency.
The XL4015 DEMO board is designed for DC-DC buck converter applications, featuring an input voltage range of 8V to 36V and a regulated 5V output capable of delivering up to 5A. The board utilizes the XL4015 switch-mode DC-DC converter chip, which operates at a fixed frequency of 180KHz to minimize external component size and facilitate EMC design. The chip includes built-in protection modules for over-current, over-temperature, and short-circuit conditions. This manual is written in Chinese.
