I-MAX8969 yi-converter elula ye-1A yesinyathelo-phezulu kwipakethe encinci esebenza kuyo nayiphi na iseli ye-Li-ion application.Le IC ibonelela ngeempawu zokukhusela ezifana negalelo lokuvalelwa kwe-undervolt yobudala, isiphaluka esifutshane, kunye nokuvalwa kobushushu obugqithisileyo.Utshintsho lwe-IC ukuya kwimodi yokutsiba ngaphandle komthungo phantsi kweemeko zomthwalo wokukhanya ukuphucula ukusebenza kakuhle.Ngaphantsi kwezi meko, ukutshintsha kwenzeka kuphela njengoko kufuneka, ukunciphisa isantya sokutshintsha kunye nokubonelela ngoku ukugcina ukusebenza kakuhle.Ukusebenza okuphezulu xa i-voltage yegalelo isondele kwi-voltage ephumayo, iindlela ezimbini ezikhethekileyo zokusebenza zikhoyo: umkhondo kunye nomzila ozenzekelayo.Ezi ndlela zivumela abasebenzisi ukuba balungelelanise i-quiescent current (IQ) kunye nexesha lokuphendula elidlulayo kwimodi yokunyusa.Kuzo zombini iindlela, i-p-channel MOSFET isebenza njengotshintsho olulinganiselweyo lwangoku ukuze i-VOUT ilandele i-VIN.Nangona kunjalo, kwimowudi yomzila, i-boost circuits ivaliwe kwaye inkqubo ilawula umsebenzi wokunyusa nge-EN, igalelo le-TREN (IQ = 30µA).Kwimowudi yokulandelela ngokuzenzekelayo (ATM), iisekethe zokunyusa zinikwe amandla kwaye isixhobo siguqulela ngokuzenzekelayo kwimodi yokunyusa xa i-VIN iwela kwi-95% ye-VOUT ekujoliswe kuyo (IQ = 60µA) .I-IC ifumaneka encinci, 1.25mm x 1.25mm , I-9-bump WLP (0.4mm pitch) iphakheji.• IiSelfowuni • Ii-smartphone • Izixhobo ze-Intanethi eziSelfowuni • GPS, PND • Ii-eBooks• UkuDityaniswa kweSistim eFlexible • Ukuya kuthi ga kwi-1A yePhulo yangoku • 2.5V ukuya ku-5.5V Uluhlu lwe-Voltage ye-Input • 3.3V ukuya ku-5.5V oKhetho lwe-Voltage ye-Output • UKhuseleko oluDityanisiweyo lonyusa ukomelela kweNkqubo • Ukuvalwa kwe-Undervoltage (UVLO) • Ukhuseleko lweSekethe ePhakamileyo Ukusebenza kakuhle kunye nezandiso zangoku eziQuiescent eziphantsi• Ngaphezulu kwe-90% eSebenzayo nge-Internal Synchronous• 60µA IQ kwiMowudi yokuTrack ezenzekelayo • 45µA IQ kwiMowudi yokuNyathelo-Up.• I-True Shutdown™ iNqanda ukuMqukuqela kwangoku ukusuka kwiOUT_ ukuya kwi-LX_ • IMida yokuQala eSofthiweyo yokuPhumeza yaNgoku ukuya kwi-480mA • Ipakethe eNcinci kunye nokuSebenza okuPhakamileyo• I-9-Bump 1.25mm x 1.25mm WLP Package • 3MHz PWM Ukutshintshela Frequency • Amacandelo amancinane angaphandle
