Application Scope:

This module can be applied to single lithium-ion batteries with 5V-12V output, for general digital product charging, such as mobile phones, iPad, MP3, PSP, etc. Equipped with a charging circuit and a battery indicator circuit, it can become a high current output mobile power supply by simply connecting the battery. You can also set the output voltage to power products between 5-12V.

Ultra small size, high work efficiency, single chip boost integrated overcurrent protection and overtemperature protection, making the circuit work more stable. The output ripple of the AVX tantalum capacitor installed in YUAN is lower. The two screw holes on the board let you not worry about how to fix them Automatic SMT mounting process, ensuring high quality
