高速电流模式脉宽调制器

LT®1241 系列器件是 8 引脚、固定频率、电流模式、脉宽调制器。它们是业界标准的 UC1842 系列的改良型插接兼容版本。这些器件兼具改善的速度与较低的静态电流。LT1241 系列专为离线式及 DC/DC 转换器应用而设计。它们内置一个温度补偿型基准、高增益误差放大器、电流检测比较器和一个高电流图腾柱输出级，非常适合于驱动功率 MOSFET。启动电流被减小至 250μA 以下。输出级中的交叉传导电流尖峰已被消除，从而使 500kHz 操作切实可行。这些器件融入了诸多新特点。电流检测比较器增加了前沿消隐功能。振荡器电路添加了针对频率和吸收电流的修整功能，并对这两个参数做了严格的规定。在导通 • 低启动电流：<250μA\n\n• 50ns 电流检测延迟\n\n• 电流模式操作：至 500kHz\n\n• 引脚与 UC1842 系列相兼容\n\n• 具迟滞的欠压闭锁\n\n• 无交叉传导电流\n\n• 经修整的带隙基准\n\n• 1A 图腾柱输出\n\n• 经修整的振荡器频率和吸收电流\n\n• 在欠压闭锁期间主动下拉基准和输出\n\n• 高电平输出箝位：18V\n\n• 电流检测前沿消隐;
