♠ TPS51396A 4.5-V kugeza 24-V, 8-Igenzura rya Intambwe-Hasi ya Voltage Igenzura hamwe na ULQ ™ Uburyo bwubuzima bwagutse bwa Bateri
TPS51396A nigiciro cyinshi, cyinjiza ingufu nyinshi, cyinjiza cyane-gihuza buck ihinduranya hamwe na FET ihuriweho.
Ikintu cyingenzi kiranga TPS51396A nuburyo bwa ULQ (Ultra Low Quiescent) kugirango bushoboze kubogama kubogamye no gukora imirimo minini. Ikiranga ULQ ni ingirakamaro cyane mubuzima bwa bateri igihe kirekire mumikorere mike. TPS51396A ikorana na voltage yinjiza itanga kuva kuri 4.5 V kugeza 24 V. Ikoresha uburyo bwo kugenzura DCAP3 kugirango itange igisubizo cyihuse, umurongo mwiza, kugenzura imizigo, nta bisabwa kugirango indishyi ziva hanze, kandi ishyigikire ubushobozi buke bwo kurwanya ibintu (ESR) busohora ibintu nka polymer yihariye na ultra-low ESR ceramic capacitor.
TPS51396A itanga uburinzi bwuzuye OVP, UVP, OCP, OTP, na UVLO. Ihujwe nimbaraga nziza ibimenyetso nibisohoka ibikorwa.
MODE pin muri TPS51396A irashobora gukoreshwa mugushiraho Eco-Mode cyangwa OOA uburyo bwo gukora imitwaro yoroheje. Eco-Mode ikomeza gukora cyane mugihe cyo gukora imizigo yoroheje, hamwe na OOA uburyo bwo guhinduranya inshuro zirenga 25 kHz nubwo nta gupakira.
TPS51396A ishyigikira byombi imbere ninyuma yoroshye-gutangira igihe. Ifite imbere yimbere yoroshye-gutangira igihe cya 1.3 ms. Niba porogaramu ikeneye igihe cyoroshye-cyo gutangira, SS yo hanze irashobora gukoreshwa kugirango ubigereho uhuza ubushobozi bwo hanze.
TPS51396A iraboneka muri 20-pin 3.0- mm × 3.0-mm ya HotRod kandi ubushyuhe bwihuza bwerekanwe kuva kuri 40 ° C kugeza kuri 125 ° C.
