3 Description

IP5305T is a highly-integrated multi-function

power management SOOC. 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.

IP5305T’s high integration and rich features make

the minimized component number in application. It

can effectively downsize the application and lower the

BOM cost.

IP5305T only needs a single inductor to realize

step-down and step-up.

IP5305T's synchronous boost system provides

1.0A output current with a conversion efficiency as

high as 91%. When no-load, it automatically enters

the sleep state, and the quiescent current drops to

100uA. +

IP5305T adopts switch charging technology,

provides 1.2A current, and the charging efficiency is as

high as 92%. Built-in IC temperature and input voltage

intelligently adjust the charging current.

IP5305T supports 1, 2, 3, 4 LED power display.

IP5305T is available in ESOP8 package.
