结合两颗TL431分流稳压器，可精准控制电流镜的电流比例，并可加入电流偏移与功率扩展… 近来在设计实例栏目中，各式各样的电流镜电路设计成为热门讨论的话题。一般而言，电流镜设计者的目标是让输入电流与输出电流精确相等，但图1所示的电路却走了 ...

In Seemingly Simple Circuits: The TL431 Voltage Regulator, Part 2, we looked at how voltage gain of the TL431 is measured. Now we plunge deeper in, to look at closed-loop output resistance, derive ...

We submerge somewhat deeper into analysis of the seemingly simple TL431 voltage reference with transconductance amplifier to find that some useful design parameters are missing from the manufacturer ...

通过浮接ANODE实现精密可编程电流吸收，并可搭配DAC或PWM控制... TL431问世至今已将近50年。在这几十年间，虽然它主要被定位为一款精密可调并联稳压器销售，但这颗经典组件也被应用于各种其他用途，包括电压比较器、音频放大器、电流源、过压保护器等。

The TL431 is a well-known voltage reference integrated circuit used in Switch-Mode Power Supply (SMPS) feedback loops. Combining a reference voltage and an open ...
