一、
概述
PWM
控制功率开关
TC6358是内½高压功率MOSFET
的电流模反激PWM 控制芯片,适用于12W 以内的全电压范围离线式反激开
关电源,具有高性½、½待机功耗、½成本的优点。
为了保证芯片正常工½,TC6358针对各种故障设计了一系列完善的具有自动恢复功½的保护措½,包括½启动、
过温保护(OTP)、VDD 欠压锁定保护(UVLO)、过压保护(OVP)及箝½、逐周期电流限制(OCP)、过½½
保护(OLP)和图腾柱输出驱动高箝½等,特别对音频噪声和FM 干扰进行了处理。芯片内½的频率抖动和图腾柱
栅极½驱动技术可容易地获得良½的EMI 性½。
二、
特点
可外部调节的MOSFET驱动½力,满足对功率输出,EMI及效率/温升的不同要求
内½频率抖动功½,改善系统的EMI特性
实现20W以下“No
Y-CAP”系统设计
超½的空½½功耗
内½4ms½启动功½
过压保护(OVP)
内½OCP补偿模块,实现优越的OCP特性
目前提供DIP8封装½式,符合RoHS标准
三、
产品应用
“No Y-CAP”
电源
DVD/DVB/机顶盒电源
电脑/服务器/液晶电视待机电源
线性电源替代
½色家电电源
