Kev piav qhia rau LMR23625
LMR23625 SWITCHER yog ib qho yooj yim-rau-siv 36-V, 2.5-A synchronous kauj ruam-down regulator.Nrog rau ntau qhov kev tawm tswv yim los ntawm 4 V txog 36 V, cov cuab yeej tsim nyog rau ntau daim ntawv thov kev lag luam rau kev siv hluav taws xob los ntawm qhov chaw tsis raug cai.Peak tam sim no-hom tswj yog ua hauj lwm kom ua tau yooj yim tswj-loop them nyiaj thiab lub voj voog-los ntawm-lub voj voog tam sim no txwv.Lub quiescent tam sim no ntawm 75 µA ua rau nws haum rau cov roj teeb uas siv hluav taws xob.Ib qho ultra-low 2 µA kaw tam sim no tuaj yeem ua kom ntev roj teeb lub neej.Internal voj them nyiaj txhais tau hais tias tus neeg siv yog dawb los ntawm tedious hauj lwm ntawm lub voj kev them nyiaj tsim.Qhov no kuj txo qis cov khoom siv sab nraud.
Cov cuab yeej muaj kev xaiv rau FPWM hom kev ruaj ntseg kom ua tiav cov zis me me-voltage ripple ntawm lub teeb load.Ib tsev neeg txuas ntxiv rau HSOIC muaj nyob rau hauv 1-A (LMR23610) thiab 3-A (LMR23630) thauj cov kev xaiv tam sim no hauv cov khoom siv pin-rau-tus pin uas tso cai yooj yim, zoo tshaj PCB layout.Lub precision enable input tso cai rau kev yooj yim ntawm regulator tswj thiab system hwj chim sequencing.Cov yam ntxwv kev tiv thaiv muaj xws li lub voj voog ntawm lub voj voog tam sim no txwv, hiccup-mode luv-circuit tiv thaiv thiab thermal kaw vim lub zog ntau dhau.
