Here is how to build a very simple 5 volt dc power supply that can deliver up to 1 5a of current.
Build 5v dc power supply.
There are more efficient and complex power supplies in the world.
Transformer after the ac plug we need a step down transformer.
The design of 5v dc power supply.
The tranformer s job is to take the 120v ac voltage from the mains line and step.
What i would like is to build a 1 2 vdc 600 milliamps power supply for led christmas lights outdoors.
Since the voltage above is for 1 set of 30 led stars 3 diameter i have 3 sets of.
But having a 3 prong plug is better because ground provides better against possible electric fires.
There are easier ways to get a simple power supply like this one re using a wall wart for instance.
I m quite familiar led s are fineky on voltage.
Ask question asked 5 years.
As most of my circuits uses 12v dc for relays etc getting 5v for a micro controller with a lcd display and it s backlight is a problem.
5v 3a dc power supply dc 5v wall plug power adapter 3 5 x 1 35mm dc jack for wireless routers camcorder dvr receiver camera battery chargers led strip lights and other devices under 15w 5 0 out of 5 stars 5.
It helps us to design the sections of the circuit individually and then at the end put them together to have a complete circuit ready for use.
But if you make a power.
Would pushing voltage to 1 3 or1 5 be ok.
In this project we will build a similar ac to dc power supply circuit with 10w power rating.
Power supply unit psu is a vital part in any electronic product design.
A regulated power supply is a very important component if you build electronics projects.
Please tell required spec of capacitors and circuit.
For the electronics enthusiast having a 5 volt dc power supply around in your workspace can be very useful.
I want to make 5v dc supply so that i can run 3 dc motors in parallel having spec 5v each and max currrent rating 900ma but i have transformer of 3amp step down transformer 220v to 12v to run lm7805 ic whose max load current is 1a.
Build your own regulated power supply.
The design of any circuit begins with a well made general block diagram.
But buying a good regulated power supply can be expensive.
Pwr supply would power all 3 sets should go to at least 2 5amps.
It can also work with a two prong ac plug.
Make 5v 3a dc power supply.
