FAN48630BUC315X

Fairchild Semiconductor### 非隔离直流/直流转换器，Fairchild Semiconductor

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.
