CXLB74217 is a versatile power management IC that integrates a step-down converter, lithium battery charge management, and battery status display to provide a complete solution for charging portable lithium batteries. The high degree of integration and built-in multiple functions of the chip make it require only a few peripheral devices in the application, and effectively reduce the size of the PCB and reduce the cost of the solution. CXLB74217 only need one inductor to achieve the buck and boost function. Its converter operates at 1MHz and can support low-cost inductors and capacitors. The CXLB74217 charging part supports (short circuit) trickle/constant current/constant voltage three-stage charging mode. In constant current mode, the chip is in constant input current mode, and its conversion efficiency is up to 90%. In addition, the chip has built-in LED display and KEY key functions, and includes multiple protection functions to maximize the reliability of the chip and the safety of the solution.
