♠ TPS255xx Saxeexa La Hagaajin Karo Qaybinta Awood-qeybsiga ee Hadda-xadaysan
Beddelka LM5007 0.5-A hoos-u-dejinta beddelka ayaa ka muuqda dhammaan hawlaha loo baahan yahay si loo hirgeliyo nidaamiye kharash yar oo hufan. Beddelaha koronto-dhaliyaha ah wuxuu leeyahay isku-dhafan 80-V, 0.7-A Nchannel buck ah wuxuuna ku shaqeeyaa in ka badan qiyaasta korantada ee 9 V ilaa 75 V. Qalabku waa sahlan yahay in la hirgeliyo waxaana lagu bixiyaa 8-pin VSSOP iyo kuleyl ahaan kor loogu qaaday xirmooyinka 8-pin WSON.
Beddeliyuhu waxa uu isticmaalaa nidaamka xakamaynta hysteretic-ka oo leh PWM-wakhtigeeda oo ka duwan VIN. Habkani waxa uu u ogolaanayaa inta jeer ee hawlgalka in ay ahaato mid joogto ah oo leh culayska iyo kala duwanaanshiyaha danab. Kantaroolka hysteretic uma baahna magdhow loop wuxuuna bixiyaa jawaab degdeg ah oo ku meel gaar ah. Xadka caqliga leh ee hadda jira waxa lagu fuliyaa wakhti fasax ah oo khasab ah kaas oo ka soo horjeeda VOUT. Nidaamkan xaddidan ee hadda jira wuxuu hubinayaa ilaalinta wareegga-gaaban iyadoo la siinayo dib-u-laabashada culeyska hadda socda. Tilmaamaha kale ee ilaalinta waxaa ka mid ah xiritaanka kulaylka oo leh soo kabasho toos ah, VCC iyo albaabka waditaanka quful yar, iyo xaddidaadda ugu badan ee wareegga shaqada.
