IP2312 Type-C 3A Rapid Charging Board Step-Down CC/CV Lithium Battery Charger Module

The IP2312 Type-C 3A Rapid Step-Down Charging Board is a highly integrated, fast-charging power management module designed for single-cell lithium polymer or 18650 batteries. Featuring a universal Type-C USB input port, this powerful synchronous buck charger efficiently converts 5V input power to safely charge batteries at up to a blazing 3A current. By utilizing advanced synchronous rectification technology, the module keeps power conversion efficiency exceptionally high, reducing thermal generation and eliminating the need for bulky heatsinks.

The module operates using a complete three-stage CC/CV (Constant Current/Constant Voltage) charging profile, ensuring safe, healthy, and complete battery replenishment. A standout feature of this board is the adjustable VSET jumper located on the back, allowing users to configure the termination voltage between standard 4.2V and high-voltage 4.35V cells. With clearly marked solder pads for direct input override (IN+/IN-) and battery connectivity (B+/B-), this micro-sized board is an ideal choice for custom power banks, DIY electronic projects, portable device modifications, and high-current battery recharging applications.
