Abstract The design of the multi-functional charging treasure with 5V DC power and solar charging dual charging mode, you can meet the needs of users in different environments。 The multifunctional charging treasure by DC voltage constitute integrated voltage regulator circuit output stable 5V DC power supply to charge a mobile phone or other electronic products; solar panels through the photovoltaic effect of the solar energy conversion into electrical energy, green can be recycled, greatly increasing the charging treasure available, convenient for the user's travel and the use。 In addition to meeting the basic charging function of the user, this paper also sets up the auxiliary function of MP3 music and lighting, and increases the entertainment function of the product, which is convenient for the user's daily needs。

The main body is pided into three parts, the first part first by 5V DC power supply charging and solar panels work principle of design charging the overall block diagram of the treasure, the second part according to the overall design diagram out of each module specific circuit, the third part finally based on Protel 99SE to design the specific principle diagram and PCB diagram implementation conforms to the requirements of the various hardware modules, debugging and ultimately the multifunctional charging treasure。 In this paper, the design of the multifunctional charging treasure philosophy is to realize charging treasure the basis of charging at the same time can increase the charge of safety and persity can not only green and safe charging, but also can bring utility and entertainment value to the user。

Keywords: Multi function; Charging treasure; Solar energy; DC power supply
