Hello everyone,
I have attached a snip image of a design I am using and have been using for almost a year and a half now...
Here is the story on the board.
(Jump down to circuit explanation if you want)
Last year, I made a few hundred using the MP2357 regulator, but since it went out of...
Hi I need Help I’m trying to make a regulator that can take variable voltage from 30v to 100v ac input to about 15v dc output if any one can help point me in the right direction or have a circuit diagram that would be great
Hi all,
I feel like I am stuck because don't know how to solve following "simple" solution:
Somehow I have to (each 60 min) activate 12V/2A electromagnet, with 5V input voltage (tipical PC USB (5V/100mA).
5V is powering microcontroller, and with that microcontroller, each 60 min I have to...
I got a high voltage regulator (Discrete using BJTs)..Attaching the circuit..would like to calculate the biasing values how its been arrived..the load at Q2A switch from 0 and 1.3A..If any one can help on theoretical calculation would be helpful
Hi,
Does anyone have any good ideas how one could build a voltage divider that can actually deliver decent current (2-3A). The traditional resistor network would not work for obvious reasons.
I want to use this on my drone, the autopilot can take between a 3 and 6 cell battery but I want to...
Hey guys.
I'm designing a series pass voltage regulator with feedback. I'm trying to disconnect the load when the load current or control element temperature exceeds a value. The attached photos show my circuit design.
The temperature cutoff circuit works as is, but the current cutoff does...
