Figure 2 Bootstrapping the IC switch voltage to the input in the circuit of Figure 1 improves efficiency by about 3%. Of course, the FET actively turns on when the source goes low. But simply using ...

A power converter generates a voltage and current for a load with all the output power coming from the input source – no energy is manufactured inside the converter and some inevitably gets used by ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
