ME8202SG是一款高度集成的电流模式PWM控制IC,针对高性能低待机功耗和经济高效的离线反激式转换器应用进行了优化.正常工作时的PWM开关频率可在外部编程,并调整至严格的范围.在空载或轻载条件下,IC以扩展"突发模式"工作,以最大限度地降低开关损耗.由此实现了更低的待机功率和更高的转换效率.VDD低启动电流和低工作电流有助于ME8202SG可靠的开机启动设计.因此,可以在启动电路中使用大阻值电阻器,以最小化待机功率.内部斜率补偿可提高系统大信号稳定性,并降低高PWM占空比输出时可能出现的次谐波振荡.电流检测输入上的前沿消隐消除了缓冲电路二极管反向恢复引起的信号毛刺,从而大大减少了设计中的外部元件数量和系统成本.ME8202提供完整的保护范围,具有自动自恢复功能,包括逐周电流限制(OCP)过载保护(OLP)VDD过压箝位和欠压闭锁(UVLO).栅极驱动输出箝位在16V,以保护功率MOSFET.在ME8202中,OCP阈值斜率经过内部优化,可在通用交流输入范围内达到恒定的输出功率限制.出色的EMI性能是通过频率混洗技术以及图腾柱栅极驱动输出的软开关控制实现的.低于20KHZ的音调能量在设计中被最小化,并且在操作期间消除了音频噪声.
