OB2576TCPA OB2576ATCPA OB2576BTCPA是一款优秀的初级侧调节电源开关，适用于中电平电源交流/直流充电器和适配器应用。该设备集成了一个内部功率MOSFET，并在QR模式下工作，提供高效率以及几个内置保护功能。OB2576TCPA 它消除了二次反馈电路的需要，以降低总材料成本。集成了专有恒压(CV)和恒流(CC)控制。
在CV控制中，控制器根据负载情况改变操作方式。在满载时，控制器在通用线路电压下以准谐振(QR)模式工作。一次侧调节电源可提供高功率，而不受DCM效率限制或可听噪声。
在CC控制中，OB2576xT对Vcs峰值电流和退磁脉冲进行采样，以调节输出电流。电流和输出功率设置可以通过CS引脚上的感应电阻Rs进行外部调整。
OB2576TCP、OB2576ATCP、OB2576BTCP提供全面的保护范围，自动恢复功能，包括逐周限流，VDD OVP, OLP, SCP, OTP等。
OB2576TCPA/OB2576ATCPA/OB2576BTCPA在高线电压空载情况下，输入功率消耗小于75mW。
OB2576TCP OB2576ATCP OB2576BTCP 采用SOP8封装。
