Introduction
IP2322 is a 5V input boost charging management IC that supports dual-cell series-connected lithium batteries/lithium-ion batteries.
IP2322 integrates power MOS and adopts a synchronous switching architecture, which requires only a few peripheral components during application, effectively reducing the size of the overall solution and reducing the BOM cost.
The IP2322 boost switching charging converter operates at a frequency of 750KHz; the maximum input charging is 2A, and the conversion efficiency is 90%.
The input voltage of IP2322 is 5V, and the input can intelligently adjust the charging current to prevent the adapter from being damaged.
IP2322 is available in DFN10 package.
