Ni agbaye ti awọn paati itanna, olutọsọna foliteji jẹ ọkan ninu lilo pupọ julọ, ṣugbọn kini IC yii ṣe?O pese a Circuit pẹlu kan asọtẹlẹ ati ki o wa titi o wu foliteji ni gbogbo igba, laiwo ti awọn input foliteji.
Bii olutọsọna foliteji ṣe ṣaṣeyọri iṣẹ-ṣiṣe yii nikẹhin si oluṣe apẹẹrẹ.Diẹ ninu awọn foliteji le jẹ iṣakoso nipasẹ diode Zener ti o rọrun, lakoko ti awọn ohun elo miiran nilo topology ilọsiwaju ti laini tabi awọn olutọsọna iyipada.Ni ipari ọjọ botilẹjẹpe, gbogbo olutọsọna foliteji ni ibi-afẹde akọkọ ati atẹle:
Alakoko:Lati ṣe agbejade foliteji ti o duro dada ti Circuit kan ni idahun si awọn iyatọ ninu awọn ipo foliteji titẹ sii.O le ni 9V sinu, ṣugbọn ti o ba fẹ 5V nikan, lẹhinna o nilo lati tẹ si isalẹ (Buck) pẹlu olutọsọna foliteji kan.
Atẹle: Awọn olutọsọna foliteji tun ṣiṣẹ lati daabobo ati daabobo ẹrọ itanna rẹ lati eyikeyi ibajẹ ti o pọju.Ohun ikẹhin ti o fẹ ni lati din-din microcontroller rẹ nitori ko le mu iwasoke ninu foliteji.
Nigbati o ba wa si fifi olutọsọna foliteji kun si iyika rẹ, iwọ yoo ṣiṣẹ deede pẹlu ọkan ninu awọn oriṣi meji – Awọn olutọsọna foliteji Linear tabi Awọn olutọsọna Foliteji Yipada.Jẹ ká wo bi mejeji ti awọn wọnyi ṣiṣẹ.
