♠ TPS62902, 3-V mpaka 17-V, Kuchita Bwino Kwambiri ndi Low IQ Buck Converter mu Phukusi la 1.5-mm × 2-mm QFN
TPS62902 ndi chosinthira champhamvu kwambiri, chaching'ono, komanso chosinthika cha DC-DC chosavuta kugwiritsa ntchito. Ma frequency osankhidwa a 2.5 MHz kapena 1.0 MHz amalola kugwiritsa ntchito ma inductors ang'onoang'ono ndipo amapereka kuyankha kwakanthawi kochepa. Chipangizochi chimathandizira kulondola kwakukulu kwa VOUT kwa ± 1% yokhala ndi topology ya DCS-Control. Ma voliyumu ambiri a 3-V mpaka 17-V amathandizira zolowetsa m'njira zosiyanasiyana, monga njanji zoperekera 12-V, cell single-cell kapena multi-cell Li-Ion, ndi njanji ya 5-V kapena 3.3-V.
TPS62902 imatha kulowa munjira yosungira mphamvu (ngati auto PFM/PWM yasankhidwa) pa katundu wopepuka kuti ikhalebe yogwira ntchito kwambiri. Kuphatikiza apo, kuti apereke magwiridwe antchito apamwamba pazonyamula zing'onozing'ono, chipangizochi chimakhala ndi mphamvu yotsika ya 4 µA. AEE, ngati yayatsidwa, imapereka magwiridwe antchito apamwamba pa VIN, VOUT, ndi katundu wapano. Chipangizocho chimaphatikizapo kulowetsa kwa S-CONF / MODE kuti mukhazikitse chogawanika chamkati / chakunja, kusintha kwafupipafupi, kutulutsa mphamvu yamagetsi, ndi njira yopulumutsira magetsi kapena kukakamiza PWM.
Chipangizocho chimapezeka mu phukusi laling'ono la 9-pin VQFN lolemera 1.50 mm × 2.00 mm ndi phula la 0.5-mm.
