i want to know how to design my own power supply for projects and how to use regulators in them and to know how to choose suitable regulators...
i have a project with a PIC18 microcontroller and which involves 2 servo motors, a ultrasound sensor and transmitter, IR sensor and transmitter, LCD and keypad... i made up a power and current table and worked out that 5V would work for each of these...however, when it comes to current, there is a requirement of about 3A when the ultrasound transmitter is sending out a pulse and about 1A when it is not.
How do i get about building my own power supply?there will be the possibility of obtaining a DC power supply from mains electricity which means i jus need a DC-DC conversion..
any online resources i can use?or any relevant chapters in books or anything?
Thanks!
