产品概述 返回TOPkjx嘉泰姆
CXCH7652 CXCH7652CM是内置高压功率MOSFET 的电流模式PWM控制芯片，适用于24W 以内的全电压范围离线式反激开关
电源，具有高性能、低待机功耗、低成本的优点。
为了保证芯片正常工作，CXCH7652 CXCH7652CM针对各种故障设计了一系列完善的具有可恢复功能的保护措施，包括软启动、
过温保护（OTP）、VDD 欠压锁定保护（UVLO）、过压保护（OVP）及箝位、逐周期电流限制（OCP）、过载
保护（OLP）和图腾柱输出驱动高箝位等，特别对音频噪声和FM干扰进行了处理。芯片内置的频率抖动和图腾柱
栅极软驱动技术可容易地获得良好的EMI 性能。</p>
