♠ LTC1474 / LTC1475 Tsawg Quiescent Tam sim no Kev Ua Haujlwm Zoo Tshaj Plaws-Down Converters
Lub LTC®1474 / LTC1475 series yog cov kev ua haujlwm siab hloov pauv nrog P-channel MOSFET lub zogkeyboards uas kos tsuas yog 10µA raug DC muab tam sim no ntawmtsis muaj load thaum tswj cov zis voltage. TSO 1474siv logic-tswj kaw thaum lub LTC1475 nta pushbutton on / off.
Cov khoom siv qis tam sim no ua ke nrog Burst ModeTM kev ua haujlwm ua rau LTC1474 / LTC1475 kom muaj kev ua haujlwm siab dhau ntau qhov kev thauj khoom. Cov nta no, nrog raunrog lawv lub peev xwm ntawm 100% lub luag haujlwm lub voj voog rau kev poob qisthiab cov khoom siv dav dav, ua rau LTC1474 / LTC1475zoo tagnrho rau nruab nrab tam sim no (txog 300mA) roj teeb-powereddaim ntawv thov.
Lub ncov hloov tam sim no yog tus neeg siv-programmable nrog ib qhoxaiv qhov kev nkag siab resistor (defaults rau 325mA yog tias tsis yogsiv) muab ib txoj kev yooj yim rau optimizing tus tsimrau cov ntawv thov tam sim no qis dua. Peak tam sim no tswjkuj tseem muab kev tiv thaiv luv luv thiab kev pib ua haujlwm zoo heev. Ib lub roj teeb uas tsis tshua muaj hluav taws xob uas tseem ua haujlwmhauv kev kaw yog muab.
Lub LTC1474 / LTC1475 series muaj nyob rau hauv 8-lead MSOPthiab SO pob khoom thiab xav tau ob peb yam ntxivmuab kev daws qhov tsawg kawg nkaus.
