♠ TPS51396A 4.5-V mpaka 24-V, 8-A Synchronous Step-Down Voltage Regulator yokhala ndi ULQ™ Mode ya Moyo Wowonjezera wa Battery
TPS51396A ndi yotsika mtengo, yolowetsa mphamvu yamagetsi, yosinthira bwino kwambiri ya buck yokhala ndi ma FET ophatikizika.
Chofunikira kwambiri pa TPS51396A ndi mawonekedwe ake a ULQ (Ultra Low Quiscent) kuti athe kugwira ntchito mopanda tsankho komanso ntchito yayikulu. Mbali ya ULQ ndiyopindulitsa kwambiri kwa moyo wautali wa batri mukugwiritsa ntchito mphamvu zochepa. TPS51396A imagwira ntchito ndi magetsi opangira magetsi oyambira 4.5 V mpaka 24 V. Imagwiritsa ntchito njira yowongolera ya DCAP3 kuti ipereke kuyankha kwakanthawi kochepa, mzere wabwino, kuwongolera katundu, palibe chofunikira pamalipiro akunja, ndipo imathandizira ma capacitor otsika ofanana (ESR) otulutsa monga ma polima apadera ndi Ultra-low capacitors ESR ceramic.
TPS51396A imapereka chitetezo chokwanira cha OVP, UVP, OCP, OTP, ndi UVLO. Ndi kuphatikiza mphamvu chizindikiro chabwino ndi linanena bungwe kutulutsa ntchito.
Pini ya MODE mu TPS51396A itha kugwiritsidwa ntchito kukhazikitsa Eco-Mode kapena OOA mode kuti igwire ntchito yopepuka. Eco-Mode imakhalabe yogwira ntchito kwambiri panthawi yonyamula zopepuka, ndipo OOA imagwira ntchito mosinthana ndi ma frequency akulu kuposa 25 kHz ngakhale osatsegula.
TPS51396A imathandizira njira yoyambira yamkati ndi yakunja. Ili ndi nthawi yokhazikika yamkati yoyambira 1.3 ms. Ngati ntchitoyo ikufunika nthawi yayitali yoyambira yofewa, pini yakunja ya SS ingagwiritsidwe ntchito kuti ikwaniritse polumikiza capacitor yakunja.
TPS51396A imapezeka mu phukusi la 20-pin 3.0- mm × 3.0-mm HotRod ndipo kutentha kwa mphumu kumatchulidwa kuchokera -40 ° C mpaka 125 ° C.
