Kev piav qhia rau TPS62242
Lub TPS6224x ntaus ntawv yog qhov ua tau zoo synchronous step-down DC-DC converter.Cov cuab yeej muab txog li 300-mA tso zis tam sim no los ntawm ib leeg Li-Ion ntawm tes thiab yog qhov zoo tagnrho rau cov roj teeb uas siv tau yooj yim xws li xov tooj ntawm tes thiab lwm yam khoom siv nqa tau.
Nrog rau qhov dav input voltage ntau ntawm 2 V rau 6 V, lub cuab yeej kuj txhawb nqa ob- thiab peb-cell alkaline, 3.3-V thiab 5-V input voltage rails.
TPS6224x ua haujlwm ntawm 2.25-MHz tsau hloov zaus thiab nkag mus rau lub zog txuag hom kev ua haujlwm ntawm lub teeb thauj khoom tam sim no kom muaj kev ua haujlwm siab dhau ntawm tag nrho cov khoom tam sim no.
Lub zog txuag hom yog optimized rau cov zis voltage ripple tsawg.Rau cov ntawv thov suab qis, cov cuab yeej tuaj yeem raug yuam mus rau hauv qhov ntsuas pulse width modulation (PWM) los ntawm rub lub MODE tus pin siab.Hauv hom kaw, qhov kev siv tam sim no raug txo kom tsawg dua 1 µA.TPS6224x tso cai rau siv cov inductors me me thiab capacitors kom ua tiav cov tshuaj me me.
Lub TPS6224x ua haujlwm tshaj qhov kub ntawm huab cua ntawm -40 ° C txog 85 ° C.Cov cuab yeej muaj nyob rau hauv 5-pin SOT thiab 6-pin 2-mm × 2-mm WSON pob.
