ip2312 single-cell lithium battery synchronous switch buck charging chip verification board

> IP2312U is a 5V input IC that supports single-cell lithium battery synchronous switching step-down charging management. IP2312U 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 IP2312U boost switching charging converter operates at a frequency of 750KHz, the maximum charging current is 3A, 5V input, 3.7V/2A conversion efficiency is 94%; the charging current can be set through an external resistor. The input voltage of IP2312U is 5V, and the input can intelligently adjust the charging current to prevent the adapter from being pulled. IP2312U is packaged in ESOP8. # Verification board description 1. For reference only, no soldering pads are reserved for current settings. 1.
