3 Description

IP5305 is a highly-integrated multi-function

power management SoC. 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.

IP5305’s high integration and rich features make

the minimized component number in application. It

can effectively downsize the application and lower the

BOM cost.

IP5305 only needs a single inductor to realize

step-down and step-up.

IP5305’s synchronous step-up converter provides

1.0A output current. Its efficiency is up to 96%. It can

switch to standby mode at empty load automatically

IP5305’s synchronous switching charger provides

1.2A charging current. Its efficiency is up to 93%. It

regulates the charging current by IC temperature and

input voltage.

IP5305 has integrated a voltage based fuel gauge

algorithm, acquiring battery’s state of charge precisely.

IP5305 is available in eSOP8.
