Introduction

Against the backdrop of rapid performance iteration in mobile devices and the growing demand for fast, efficient charging, fast-charging technology is emerging as one of the core tracks in the consumer electronics sector. However, challenges such as limited multi-protocol compatibility, poor high-power output stability, and difficulties in balancing device size with heat dissipation continue to hinder the design and innovation of charging equipment.

Injoinic’s IP2756 addresses these challenges by offering a highly efficient and safe solution for single-direction output devices such as adapters and car chargers, with its key advantages including full protocol coverage, high-voltage tolerance, and flexible scalability.

Injoinic IP2756

The Injoinic IP2756 is a fast-charging protocol controller IC designed for USB ports, integrating support for multiple charging protocols. It supports a wide range of fast-charging standards, including PD2.0/PD3.1 SPR & EPR up to 36V, HVDCP, QC5/4+/3+/3.0/2.0, FCP, SCP, AFC, UFCS, Apple 2.4A, BC1.2, and Samsung 2.0A. It provides a comprehensive solution for single-direction output applications such as adapters and car chargers.

The IP2756 offers a higher voltage tolerance, supporting EPR 28V–36V with a simplified peripheral design. Through expansion, it can further support EPR up to 48V while providing larger memory capacity. In multi-protocol applications, customers no longer need to compromise between protocols. The IP2756 delivers enhanced ESD protection, significantly improving product reliability and supporting a wider current range.

Here is the information about Injoinic IP2756.
