一,产品概述(General Description) 
The CXLB7341CS is a complete, cost effective, high- efficient solution for Li-Ion Battery Powered Mobile Supply.
VBAT is a complete constant-current/constant voltage linear charger for one cell lithium-ion battery. The charge
current of pre-charging and constant–current charging is adjustable and it can be programmed to 1A. An external sense
resistor sets the charge current with high accuracy.VOUT5 (5V) is a step-up DC/DC converter with internal power MOSFETs.
It achieves 2A (with 2318 NMOSFET) continuous output current over a wide input supply range with excellent load and line
regulation. In addition, the CXLB7341CS can be used as a flashlight.
The CXLB7341SC is available in a low profile TSSOP-16L package and The CXLB7341CSS is available in a low profile
SOP-16 package.
