  • LM3524D-调整脉宽调制器

    LM3524D家庭是一个行业的改进版本标准的LM3524。它改善了规范的和额外的的功能引脚对引脚兼容现有的3524家庭。新特性减少了需要额外的外部电路通常需要在原来的版本。LM3524D具有±1％高精度5V参考。目前的输出驱动晶体管的承载能力已被提高到200毫安，同时减少VCESAT和增加VCE的60V的击穿。共模电压范围误差放大器已提高至5.5V，以消除需要一个电阻分压器从5V参考。LM3524D电路的偏置线已被隔离关机引脚。这可以防止振荡器的脉冲幅度从关机的干扰频率。另外在高频率（.300kHz）的最大值。每股占空比产量已提高到44％比35％以下。他3524s占空比。此外，LM3524D
