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. IP5306’s high integration and rich features make the minimized component number in application. It can effectively downsize the application and lower the BOM cost. IP5306 only needs a single inductor to realize step-down and step-up which provides 2.4A output current. It can switch to standby mode at light load automatically IP5306’s synchronous switching charger provides 2A charging current. Its efficiency is up to 91%. It regulates the charging current by IC temperature and input voltage.。 IP5306 integrates voltage based fuel gauge indication of 1/2/3/4 LEDs and flashlight function. IP5306 is available in ESOP8 V1.31 http://www.injoinic.com/ 1 / 11 Copyright © 2016, Injoinic Corp.
