I-TPS61099YFFR Ishintsha Izilawuli Ze-Voltage 0.7Vin Synchronous Boost Converter ene-800 nA Ultra-Low Quiscent Yamanje 6-DSBGA -40 kuya ku-85

Idivayisi ye-TPS61099x iyisiguquli se-boost esivumelanayo esine-1-µA yamanje ethule kakhulu ephansi kakhulu. Idivayisi yakhelwe imikhiqizo enikwa amandla ibhethri le-alkaline, ibhethri le-NiMH elishajekayo, ibhethri le-Li-Mn, noma ibhethri ye-Li-Ion ekwazi ukushajwa kabusha lapho ukusebenza kahle okuphezulu ngaphansi kwesimo sokulayisha ukukhanya kubalulekile ukuze kuzuzwe ukusebenza kwebhethri isikhathi eside.

Isiguquli se-TPS61099x se-boost sisebenzisa i-hysteretic control topology ukuze sithole ukusebenza kahle okuphezulu ngesikhathi esincane esithule. Isebenzisa kuphela i-1-µA yamanje ethule ngaphansi kwesimo sokulayisha ukukhanya futhi ingafinyelela ukusebenza kahle okungafika kokungu-75% ekulayisheni okungu-10-µA ngenguqulo ye-voltage ephumayo engaguquki. Ingakwazi futhi ukusekela okukhiphayo okungafika ku-300-mA wamanje kusuka ku-3.3-V kuya ku-5-V ukuguqulwa, futhi ifinyelele kufikela ku-93% ekulayisheni okungu-200-mA.

I-TPS61099x iphinde inikeze kokubili Imodi ephansi kanye nokusebenza kwe-Pass-Through kwezinhlelo zokusebenza ezahlukene. Kumodi ethi Phansi, i-voltage ephumayo isengalawulwa kunani eliqondiwe ngisho noma i-voltage yokufaka iphezulu kune-voltage ephumayo. Kumodi ye-Pass-Through, i-voltage ephumayo ilandela i-voltage yokufaka. Idatha ye-TPS61099x
iphuma kumodi ethi Phansi bese ingena kumodi yokudlula lapho i-VIN > VOUT + 0.5 V.

I-TPS61099x isekela umsebenzi wokuvala shaqa wangempela lapho ukhutshaziwe, okunqamula umthwalo ekunikezeni okokufaka ukuze kuncishiswe ukusetshenziswa kwamanje.

I-TPS61099x inikeza kokubili inguqulo ye-voltage ekhishwayo eguquguqukayo kanye nezinhlobo ze-voltage eziphumayo ezingaguquki. Itholakala ku-6-ball 1.23-mm × 0.88-mm WCSP Iphakheji kanye ne-6-pin 2-mm × 2-mm iphakheji ye-WSON.
