LM22672 switching regulator muab tag nrho cov haujlwm tsim nyog los ua kom muaj txiaj ntsig zoo ntawm qhov hluav taws xob qis qis (pw) regulator siv qhov tsawg kawg nkaus ntawm cov khoom sab nraud.Qhov no yooj yim rau siv regulator suav nrog 42 V N-channel MOSFET hloov muaj peev xwm muab tau txog li 1 A ntawm kev thauj khoom tam sim no.Cov kab zoo heev thiab kev tswj hwm kev thauj khoom nrog rau kev ua haujlwm siab (> 90%) yog featured.Voltage hom tswj muaj qhov tsawg kawg nkaus ntawm lub sijhawm, tso cai rau qhov dav tshaj qhov sib piv ntawm cov tswv yim thiab cov zis voltages.Internal voj kev them nyiaj txhais tau hais tias tus neeg siv yog dawb los ntawm lub tedious hauj lwm ntawm xam lub voj kev them nyiaj Cheebtsam.Tsau 5 V tso zis thiab adjustable tso zis voltage xaiv muaj.
Lub neej hloov pauv zaus yog teem rau ntawm 500 kHz uas tso cai rau cov khoom me me sab nraud thiab cov lus teb zoo ib ntus.Tsis tas li ntawd, qhov zaus tuaj yeem hloov kho ntau ntawm 200 kHz mus rau 1 MHz nrog ib qho kev tawm tsam sab nraud.Lub oscillator sab hauv tuaj yeem synchronized rau lub moos moos lossis mus rau oscillator ntawm lwm tus tswj hwm.Lub precision enable input tso cai rau kev yooj yim ntawm regulator tswj thiab system hwj chim sequencing.Hauv hom kaw lub regulator tsuas yog 25 µA (typ).Ib qho adjustable soft-start feature yog muab los ntawm kev xaiv ntawm ib tug sab nraud capacitor.Lub LM22672 kuj tau tsim nyob rau hauv thermal kaw, thiab tam sim no txwv los tiv thaiv kev sib tsoo overloads.
LM22672 yog ib tug tswv cuab ntawm Texas Instruments 'SIMPLE SWITCHER® tsev neeg.Lub tswv yim yooj yim SWITCHER® muab kev yooj yim rau kev siv ua tiav kev tsim siv tsawg kawg ntawm cov khoom siv sab nraud thiab TI WEBENCH® tsim cov cuab yeej.TI's WEBENCH® cov cuab yeej suav nrog cov yam ntxwv xws li kev suav sab nraud, hluav taws xob simulation, thermal simulation, thiab Build-It boards kom yooj yim tsim-hauv.
