The IP5306 is a fully integrated multi-function power management SoC from Injoinic Technology Co., Ltd. It integrates a boost converter, a Li battery charger management system, and a battery state of charge indicate controller. It provides a turn-key solution for power bank and portable charger applications.

The IP5306's high integration and rich features make it possible to minimize the component count in the application. This can effectively downsize the application and lower the BOM cost. The IP5306 only needs a single inductor to realize step-down and step-up, which provides a 2.4A output current.

The IP5306's synchronous switching charger provides a 2A charging current with an efficiency of up to 91%. It regulates the charging current based on IC temperature and input voltage. The IP5306 also integrates voltage-based fuel gauge indication of 1/2/3/4 LEDs and a flashlight function.

The IP5306 is available in an ESOP8 package, making it ideal for space-constrained applications.
