AC-DC芯片LP3773ABCD

芯片概述（Summary）

CX7501是一款高性能的谐振高精度CV/CC电流模式PWM的控制芯片，在CV模式下，采用多模式QR控件，使用AM的（振幅）调制方式和（频率调制）调频模式，提高系统效率和可靠性。在CC模式下，IC采用PFM控制线路以及负载CC补偿。

CX7501 is a high performance PWM power switch with high precision CV/CC control ideal for charger applications. In CV mode, It adopts Multi Mode QR Control which uses the hybrid of AM (Amplitude Modulation) mode and (Frequency Modulation) FM mode to improve system efficiency and reliability. In CC mode, the IC uses PFM control with line and load CC compensation.
