[PICLIST] Transformerless PSU by "Alexandre Domingos F. Souza" .

Dear guys, I think it's a basic one, but maybe fits the list I designed a circuit with a PIC (12C508) that turns on and off a relay, controlled by an external source. The power to this circuit (around 120mA) is a small transformer. I'd like to build a transformerless PSU into this circuit. But EVERY scheme I found on the internet was unusable. I saw something on the Embeeded Control Handbook from Microchip, but it only goes to (if I'm not mistaken) 45 mA. Maybe someone can help me to develop (or at least learn to) a simple transformerless PSU that can give me 12vcc / 120 mA??? Thanks for any info! :o) ---8<---Corte aqui---8<---- Alexandre Souza @spam@taitospamBeGonespam_OUTterra.com.br http://planeta.terra.com.br/lazer/pinball/ ---8<---Corte aqui---8<---- -- http://www.piclist.com hint: To leave the PICList spampiclist-unsubscribe-requestTakeThisOuT.....mitvma.mit.edu
