♠ LM46002 3.5-V to 60-V, 2-A Synchronous Step-Down Voltage Converter
Isilawuli se-LM46002 iyisiguquli esisebenziseka kalula sokuya phansi se-DC/DC esikwazi ukushayela kufikela ku-2 A womthwalo wamanje usuka ku-voltage wokufaka osuka ku-3.5 V ukuya ku-60 V. I-LM46002 inikeza ukusebenza kahle okukhethekile, ukunemba kokukhishwayo nokwehla. -out voltage ngosayizi wesixazululo esincane kakhulu.Umndeni onwetshiwe uyatholakala ngezinketho zamanje zomthwalo ohlukahlukene kanye ne-voltage ephezulu engu-36-V yokufaka kumaphakheji ahambisanayo wephini-to-pin, okuhlanganisa i-LM46001, LM46000, LM43603, LM43602, LM43601 kanye ne-LM43600.Ukulawulwa kwe-Peak-currentmode kusetshenziselwa ukuzuza isinxephezelo esilula se-controlloop kanye nomkhawulo wamanje womjikelezo nomjikelezo.Izici ongazikhetha ezifana nemvamisa yokushintsha ehlelekayo, ukuvumelanisa, ifulegi elihle lamandla, ukunika amandla ukunemba, isiqalo esithambile sangaphakathi, isiqalo esithambile esinwebekayo, nokulandelela kunikeza inkundla eguquguqukayo nesebenziseka kalula yohlu olubanzi lwezinhlelo zokusebenza.Ukuqhutshwa okungaqhubeki nokunciphisa imvamisa okuzenzakalelayo ekulayishweni kokukhanya kuthuthukisa ukusebenza kahle komthwalo wokukhanya.Umndeni udinga izingxenye ezimbalwa zangaphandle.Ukuhlelwa kwephinikhodi kuvumela isakhiwo se-PCB esilula, esikahle.Izici zokuvikela zifaka ukuvala shaqa okushisayo, ukuvala i-VCC undervoltage, umkhawulo wamanje womjikelezo nomjikelezo, nokuvikelwa kokukhishwa kwesekethe emfushane.Idivayisi ye-LM46002 iyatholakala kuphakheji ye-HTSSOP / PWP ehola phambili engu-16 (6.6 mm × 5.1 mm × 1.2 mm) enephimbo eliholayo elingu-0.65-mm.
