Mobile charger PCB Board

Description

About this item:

This Mobile Charger PCB Board is a compact Switch Mode Power Supply (SMPS) circuit designed for safe and efficient USB charging. Supporting a wide input range of 100V–240V AC at 50/60 Hz, the board is ideal for mobile chargers, DIY power adapters, and portable electronics.

The circuit employs transformer isolation for safety and provides a regulated 5V DC output with a current capacity typically between 0.5A and 2.1A, enabling it to charge smartphones, tablets, Bluetooth devices, and other USB-powered gadgets.

Built on a single-sided PCB, the design is lightweight and space-efficient, usually measuring around 3–4 cm square, making it suitable for integration into small enclosures.

To ensure reliability, the board includes surge protection (MOVs) and integrated overcurrent and short-circuit protection managed by the SMPS controller.
