♠ Isilawuli se-GreenChip esivumelanayo esikabili
I-TEA1995T iwumkhiqizo wokuqala wesizukulwane esisha sesilawuli se-Synchronous Rectifier (SR) ICs sokunikezwa kwamandla kwemodi eshintshiwe. Ihlanganisa indlela ye-adaptive gate drive ukuze isebenze kahle kunoma yimuphi umthwalo.
I-TEA1995T iyisilawuli esizinikezele se-IC sokulungiswa okuvumelanayo ohlangothini lwesibili lweziguquli ezinomsindo. Inezigaba ezimbili zomshayeli zokushayela ama-SR MOSFETs, alungisa imiphumela yamawindi e-transformer yesibili kampompi emaphakathi. Izigaba ezimbili zomshayeli wesango zinezinzwa zazo futhi zisebenza ngokuzimela.
I-TEA1995T ingasetshenziswa futhi kuma-multi-output flyback converters kanye ne-SR MOSFET ebekwe ohlangothini oluphansi.
I-TEA1995T yenziwe ngenqubo ye-Silicon-On-Insulator (SOI).
2.1 Izici zokusebenza kahle
• I-Adaptive gate drive ukuze isebenze kahle kunoma yimuphi umthwalo
• Nikeza okwamanje ekusebenzeni kokulondoloza amandla ngaphansi kuka-200 μA
2.2 Izici zohlelo lokusebenza
• Ibanga lamandla kagesi elibanzi ukusuka ku-4.5 V ukuya ku-38 V
• Ukulungiswa okukabili kokuvumelanisa kwe-LLC resonant kuphakheji ye-SO8
• Ukulungiswa okuhambisanayo kweziguquli ze-flyback zemiphumela eminingi
• Isekela ukusebenza okungu-5 V ngezinga elinengqondo le-SR MOSFETs
• Okokufaka okuhlukile kokuzwa ukuphuma kwamanzi kanye namandla omthombo we-SR MOSFET ngayinye
2.3 Izici zokulawula
• Ukulawulwa kwe-SR ngaphandle kwenani elincane ngesikhathi
• I-Adaptive gate drive yokucisha ngokushesha ekupheleni kokushayela
• Ukuvikelwa kwe-UnderVoltage LockOut (UVLO) ngokudonsela phansi kwesango okusebenzayo
I-TEA1995T ihloselwe ukuphakela amandla anomsindo. Kulezi zinhlelo zokusebenza, ingashayela ama-MOSFET amabili angaphandle wokulungisa ama-voltage ukuze kulungiswe ama-voltage kumawindi amabili esibili e-transformer. Lawa ma-MOSFET athatha indawo yama-diode. Ingasetshenziswa kukho konke ukunikezwa kwamandla okudinga ukusebenza kahle okuphezulu:
• Ama-adaptha
• Izinsiza zamandla ze-PC yedeskithophu kanye ne-PC yakho konke
• Izinsiza zamandla zikamabonakude
• Izinsiza zamandla zamaseva
