Kev piav qhia rau LM5160
LM5160 / A yog 65-V, 2-A synchronous kauj ruam-down converter nrog integratedhigh-sab thiab qis-sab MOSFETs.Lub tswv yim tswj kev hloov pauv tsis tu ncua ntawm lub sijhawm yuav tsum tsis muaj lub voj voog rov qab thiab txhawb nqa cov theem qis qis nrog cov lus teb ceev ceev.Ib qho kev tawm tswv yim sab hauv tswj hwm ± 1% tso zis hluav taws xob tswj hwm tag nrho cov kev khiav hauj lwm kub.Theon-lub sij hawm sib txawv inversely nrog input voltage uas ua rau yuav luag tas li switchingfrequency.
Peak thiab hav tam sim no txwv circuits tiv thaiv cov xwm txheej overload.Theundervoltage lockout (EN/UVLO) Circuit Court muab nws tus kheej adjustable input undervoltagethreshold thiab hysteresis.LM5160 / A yog programmed los ntawm FPWM tus pin los ua haujlwm hauv kev ua haujlwm tsis tu ncua (CCM) los ntawm tsis muaj kev thauj khoom mus rau tag nrho cov khoom thauj lossis hloov mus rau qhov tsis sib xws (DCM) ntawm lub teeb thauj khoom kom ua haujlwm tau zoo dua.Kev quab yuam CCM kev ua haujlwm txhawb nqa ntau-tso tawm thiab cais Fly-Buck daim ntawv thov siv lub inductor txuas.
Lub LM5160A qhia tib yam nta thiab tus pin configuration li LM5160.Ib qho khoom siv sab nraud tuaj yeem txuas nrog VCC tus pin ntawm LM5160A hauv Buck thiab Fly-Buckapplications.Qhov kev muaj peev xwm ntxiv no txo qis IC lub zog dissipation thiab txhim kho kev ua haujlwm ntawm high input voltages.
