【应用】国产可调式精密并联稳压器助力开关电源设计,工作结温-40~+125℃,最大输出电流100mA
开关电源被誉为节能、高效型电源,因其高集成度、高性价比、外围电路简单等优势,已获得广泛应用。如下图所示,开关电源包括了输入整流滤波器、功率开关管及高频变压器、控制电路、输出整流滤波器和反馈电路,本文介绍的SGM431BXN3LG/TR就应用于反馈电路中。
精密光耦反馈电路是由光耦合器和可调式精密并联稳压器构成的,SGM431BXN3LG/TR此处可以用来替换普通的稳压管,构成外部误差放大器,进而对输出电压做出精细调整。当输出电压产生波动时,将经电阻分压后得到的取样电压和SGM431BXN3LG/TR中的2.5V参考电压进行比较,在阴极形成误差电压,使得光耦中的LED工作电流产生变化,再通过光耦去改变开关电源的控制端电流,进而调节输出占空比,使输出电压不变,达到稳压的目的。
下面是圣邦微SGM431BXN3LG/TR应用在此处的优势:
1、SGM431在+25℃时的参考电压公差为标准等级1%,SGM431B为B级0.5%,输出电压可调Vref至36V,最大输出电流100mA;
2、输出典型阻抗值0.1Ω,工作结温范围:-40℃至+125℃,温漂典型值5mV,保障了温度范围内的稳定性,有利于整个产品系统的稳定性;
3、国产厂牌,供货相较稳定、有保障,可帮助降低研发成本、缩短研发周期,为客户研发生产保驾护航。
以下为SGM431BXN3LG/TR引脚图:
综上述:SGM431BXN3LG/TR可应用于开关电源SMPS的次级侧调节电路。
