3 Introduction

IP5407 is a multi-function power management soc with integrated boost converter, lithium battery charge management, and battery power indication, providing a complete power solution for mobile power.

IP5407 has high integration and rich functions, so it only needs few peripheral devices in application，effectively reduce the size of the overall solution and reduce BOM cost.

IP5407's synchronous boost system provides 2.1A / 2.4A output current, and the conversion efficiency is as high as 93. At light load, it automatically turns off the LED power indicator and maintains the 5V voltage output to sleep, and the quiescent current drops below 150uA.

IP5407 uses switch charging technology to provide 2.0a current at the input, with charging efficiency up to 91.Built-in IC internal temperature and input voltage detection and intelligent adjustment of charging current. IP5407 supports 4, 2, 1 LED power display and lighting functions. IP5407 is available in ESOP8 package.
