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.
