Portable battery charger electronic PCBA design

Short Description:

Ensure that the charging circuit is compatible with the type and capacity of the battery being used. Power Management: Integrate a power management IC to convert the input power supply (e.g., AC mains or USB power) to the required voltage for the charging circuit and the OLED screen.
The electronic PCBA design power management IC should also provide necessary protection features like overvoltage protection, overcurrent protection, and thermal protection. Microcontroller Unit (MCU): Select a microcontroller unit that can control the charging process and interface with the OLED screen.
Working with an experienced electrical engineer or PCB designer can help ensure the successful implementation of the PCBA solution for your battery charger with an OLED screen.
