♠ TPS54388C-Q1 Magalimoto 2.95-V mpaka 6-V, 3-A , 2-MHz Synchronous Buck Converter
Chipangizo cha TPS54388C-Q1 ndi chodzaza ndi 6-V, 3-A, chosinthira chosinthira pakali pano chokhala ndi ma MOSFET awiri ophatikizika.
Chipangizo cha TPS54388C-Q1 chimathandizira mapangidwe ang'onoang'ono pophatikiza ma MOSFET, kugwiritsa ntchito njira zamakono zochepetsera kuwerengera kwazinthu zakunja, kuchepetsa kukula kwa inductors pothandizira mpaka 2-MHz kusintha pafupipafupi, ndikuchepetsa IC footprint ndi phukusi laling'ono la 3-mm × 3-mm motenthetsera QFN.
Chipangizo cha TPS54388C-Q1 chimapereka malamulo olondola a katundu wosiyanasiyana wokhala ndi ± 1% voliyumu yolondola (Vref) pa kutentha.
Ma MOSFET ophatikizika a 12-mΩ ndi 515-μA momwe amaperekera pano amakulitsa magwiridwe antchito. Kulowetsa njira yotsekera pogwiritsa ntchito pini yolumikizira kumachepetsa kutsekeka komwe kulipo mpaka 5.5 µA, momwemo.
Kuyika kwamkati kwa undervoltage Lockout kuli pa 2.45 V, koma kukonza malo okhala ndi netiweki yotsutsa pa pini yolumikizira kumatha kukulitsa zoikamo. Pini yoyambira pang'onopang'ono imayika poyambira-voltage poyambira. Chizindikiro champhamvu chotsegula-chabwino chimasonyeza pamene zotulukazo zili mkati mwa 93% mpaka 107% yamagetsi ake.
Kupindika kwafupipafupi ndi kuzimitsa kwa kutentha kumateteza chipangizocho pakadutsa mafunde.
• AEC-Q100-oyenerera kugwiritsa ntchito magalimoto:
- Kutentha giredi 1: -40°C mpaka +125°C, TA
