LINEAR TECHNOLOGY LT3462ES6 kunye LT3462AES6 Inverting DC/DC Converters

INKCAZO

Umboniso wesekethe ye-670 ubonisa i-frequency ezimbini eziphezulu, i-monolithic LT3462 kunye ne-LT3462A inverting converters. Zombini iisekethe zine-5V yokufaka ivolthitage kunye -5V imveliso ye-volt-age kunye ne-100mA ephezulu yemveliso yangoku. Itopology ye-SEPIC yokuguqula engalunganga isetyenziselwa ukunciphisa igalelo kunye nemveliso yevoltage ripple. Isekethe ye-LT3462 ilungiselelwe ukuba isebenze ngokugqibeleleyo nge-1.2MHz yokutshintsha okuphindaphindiweyo. Isekethe ye-LT3462A ilungiselelwe ubuncinci besayizi yesekethe kunye neprofile kunye ne-2.7MHz yokutshintsha amaxesha amaninzi. Zombini iisekethe zinesayizi encinci yeenyawo ngenxa yediode edibeneyo yeSchottky ngaphakathi kwe-ICs.

Yila files kule bhodi yesekethe ziyafumaneka. Fowunela umzi-mveliso we-LTC.
I-LT luphawu lwentengiso lwe-Linear Technology Corporation

INKQUBO YOKUQALA NGOKUKHAWULEZA
Isekethe yokubonisa i-670 kulula ukuseta ukuvavanya ukusebenza kwe-LT3462 kunye ne-LT3462A. Jonga kuMfanekiso 1 wokuseta isixhobo somlinganiselo ofanelekileyo kwaye ulandele le nkqubo ingezantsi:

PHAWULA: Xa ulinganisa igalelo okanye umthamo wemvelisotage ripple, kufuneka kuthathelwe ingqalelo ukuphepha umhlaba omde okhokelela kwi-oscilloscope probe. Ukulinganisa igalelo okanye umthamo wemvelisotage ripple ngokuchukumisa incam probe ngqo ngapha Vin okanye Vout kunye GND terminals. Jonga uMfanekiso 2 ngobuchule obufanelekileyo bokuhlola umda.

1. Beka zombini i-ON/OFF jumpers kwindawo ye-ON.
2. Xa ucinyiwe umbane, qhagamshela i-5V igalelo lamandla ombane kwi-VIN kunye ne-GND. Qhagamshela umthwalo phakathi kwe-VOUT kunye ne-GND. Seta kwangaphambili umthwalo wangoku kwi-0A (ubuncinci).
3. Vula amandla kwigalelo.
   PHAWULA: Qinisekisa ukuba igalelo voltagi-e ayidluli kwi-5.5V.
4. Jonga umthamo wemveliso ofanelekileyotages. I-Vout = -4.85V ukuya -5.15V.
   PHAWULA: Ukuba akukho mveliso, khulula okwethutyana umthwalo ukuze uqiniseke ukuba umthwalo awubekwanga phezulu kakhulu.
5. Xa imveliso eyiyo voltagii-es zisekiwe, zilungelelanise imithwalo ngaphakathi koluhlu olusebenzayo kwaye ziqwalasele umthamo wemvelisotage ummiselo, ripple voltage, ukusebenza kakuhle kunye nezinye iiparamitha.

Umzobo 1. Ukusekwa kweZixhobo zoMlinganiso oLungileyo
(a) LT3462ES6 ukuseta uvavanyo, (b) LT3462AES6 ukuseta uvavanyo
