Tshiab Original Integrated Circuit TPS63070RNMR

luv luv piav qhia:

Lub TPS6307x yog ib tug high efficiency, tsis tshua muaj quiescent tam sim no buck-boost converter haum rau daim ntaub ntawv uas lub input voltage yuav siab dua los yog qis dua qhov tso zis voltage.Cov zis tam sim no tuaj yeem mus siab li 2 A hauv boost hom thiab hauv hom phaw.Lub pulse-boost converter yog ua raws li lub sijhawm ruaj khov, pulse-width modulation (PWM) maub los siv synchronous rectification kom tau txais kev ua haujlwm siab tshaj plaws.Thaum tsis tshua muaj load tam sim no, lub converter nkag mus rau lub hwj chim Txuag hom kom muaj kev ua tau zoo tshaj ib tug dav load tam sim no ntau yam.Lub converter tuaj yeem raug kaw kom txo qis roj teeb.Thaum lub sij hawm kaw, lub load yog disconnected ntawm lub roj teeb.Cov cuab yeej muaj nyob rau hauv 2.5 mm x 3 mm QFN pob.

Taw qhia

Lub regulator hloov (DC-DC converter) yog ib tug regulator (stabilized fais fab mov).Lub tshuab hluav taws xob hloov pauv tuaj yeem hloov pauv qhov hluav taws xob ncaj qha tam sim no (DC) rau qhov xav tau ncaj qha tam sim no (DC) voltage.
Hauv ib lub tshuab hluav taws xob lossis lwm yam khoom siv, lub tshuab hluav taws xob hloov hluav taws xob siv lub luag haujlwm ntawm kev hloov hluav taws xob los ntawm lub roj teeb lossis lwm lub zog hluav taws xob mus rau qhov hluav taws xob uas xav tau los ntawm cov tshuab tom ntej.

Raws li cov lus piav qhia hauv qab no qhia tau hais tias, lub tshuab hluav taws xob hloov hluav taws xob tuaj yeem tsim cov zis hluav taws xob (V_Tawm) uas siab dua (step-up, boost), qis dua (step-down, puck) los yog muaj polarity txawv dua li qhov input voltage (V_IN)
Hloov cov yam ntxwv regulator

Cov hauv qab no muab cov lus piav qhia ntawm cov yam ntxwv tsis sib xws ntawm kev hloov pauv regulator.

Kev ua haujlwm siab

Los ntawm kev xa cov khoom hloov pauv ON thiab OFF, lub tshuab hloov hluav taws xob ua kom muaj hluav taws xob hloov pauv tau zoo vim nws muab cov khoom siv hluav taws xob tsuas yog thaum xav tau.
Ib tug linear regulator yog lwm hom regulator (stabilized fais fab mov), tab sis vim hais tias nws dissipates ib qho nyiaj seem li tshav kub nyob rau hauv lub voltage conversion txheej txheem ntawm VIN thiab VOUT, nws tsis yog yuav luag npaum li ib tug hloov regulator.
Ib tug linear regulator yog lwm hom regulator (stabilized fais fab mov), tab sis vim hais tias nws dissipates ib qho nyiaj seem li tshav kub nyob rau hauv lub voltage conversion txheej txheem ntawm VIN thiab VOUT, nws tsis yog yuav luag npaum li ib tug hloov regulator.

Suab nrov

Lub caij hloov pauv ON / OFF ua haujlwm hauv lub tshuab hloov pauv ua rau muaj kev hloov pauv tam sim no hauv qhov hluav taws xob thiab tam sim no, thiab cov kab mob cab uas ua rau lub suab nrov, tag nrho cov uas qhia lub suab nrov hauv cov zis hluav taws xob.
Kev siv lub rooj tsav xwm tsim nyog muaj txiaj ntsig zoo hauv kev txo cov suab nrov.Piv txwv li, optimizing qhov chaw ntawm capacitor thiab inductor thiab / los yog thaiv.Yog xav paub ntxiv txog cov txheej txheem ntawm yuav ua li cas lub suab nrov (ntiv nplhaib) raug tsim thiab tswj nws li cas, xa mus rau Daim Ntawv Ceeb Toom "Qib-Down Switching Regulator Noise Countermeasures."
