Simple DC to DC step up converter using TDA2822

Electronic projects circuits Collection of electronic circuits with PCB layout View this email in your browser This is a simple DC to DC step up converter circuit which can increase input voltage of 3-12 volts into 4.5-22 volts at current 1-300 mA. It use small audio amplifier IC as main and use principle doubler voltage 2 times with diode and capacitor only without coil or transformer. So this circuit is easy and cheap. I like them. How does it work. "DC to DC Step up converter" is one other the switching regulator, transform low voltage into high voltage by raise level the voltage output is 2 times. of input voltage. .[...] Read more Note: You can see a lot of projects at : Mini Projects and Cool projects Facebook Twitter Website Email Google Plus Copyright © 2014 Eleccircuit.com, All rights reserved. unsubscribe from this list    update subscription preferences
