IP2312-4V35 Single Cell Lithium Battery Charging IC

The IP2312 is a 5V input that supports single-cell Li-Ion battery synchronization IC for switching buck charge management. IP2312 integrated power MOS with synchronous switching architecture enables. It requires only a few peripheral components for the application and effectively reduces the overall situation. The size of the scheme to reduce BOM cost.

IP2312 boost switching charge converter operating frequency 750KHz, maximum charging current is 3A, 5V input, 3.7V/2A revolution Exchange efficiency 94%; The charging current can be set by an external resistor.

The IP2312 input voltage is 5V, and the input can intelligently adjust the charging current, preventing pulling on the adapter.
