FAN48630UC45X集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

描述 Description

The FAN48630 allows systems to take advantage of new battery chemistries that can supply significant energy when the battery voltage is lower than the required voltage for system power ICs. By combining built-in power transistors, synchronous rectification, and low supply current; this IC provides a compact solution for systems using advanced Li-Ion battery chemistries.
