Circuit alimentation

Former Member
Former Member over 14 years ago

Je souhaites créer un petit circuit de lecture de puce dallas avec bluetooth, alimenté sur 2 piles 1.5V AAA. Simplement j'ai besoin d'une tension de 3V au minimum en permanence, je ne trouve pas le petit circuit qui ferais mon bonheur, à savoir ne pas trop consommer au repos (voir rien !) et me fournir une tension constante de 3V même avec pile très faible. Avez-vous une idée ?

 

 

Petit UP !

 

Après encore pas mal de recherche, je suis tombé sur ce circuit qui m'a l'air très bien : http://fr.farnell.com/jsp/search/productdetail.jsp?sku=1663904

Je vous tiens au courant !

    Convert AC to 5V DC: Tracopower TMLM 04105Tracopower TMLM 04105

    Then regulate it down to 3V: TEXAS INSTRUMENTS - TPS73030DBVTTEXAS INSTRUMENTS - TPS73030DBVT
