I would like to ask about the boost chip TPS61021A. When powered by a battery, the initial battery voltage is 3.6V. As the battery power decreases, the voltage changes to 2V, while the output is a sta...
[i=s] This post was last edited by learntest on 2019-4-15 12:25 [/i]Where does he get this 26mV? ? 26mV should be the voltage of VE, right? Because re=26mV/ie, but why is ve 1.2v? 81*(26mv/ie)=50 ohms...
1. Given a fixed value of V1: 0.5V, the value of v2 is adjustable. 2.When 0.5V＜V2＜1V (approximately this value, there may be some difference above or below), the OUT output is my ideal output value.Qu...
