5. Vula ukunikezwa kwamandla kokokufaka. Ikhuphula kancane ivolumu yokufakatage ukusuka ku-0V ukuya ku-12V (okujwayelekile). Linganisa futhi uqinisekise umthamo wokufakwayo wokufakwayotagI-e ingu-12V bese upheqa u-SWR0 (RUN0) endaweni ethi ON. Umthamo wokukhiphatagi-e kufanele ibe ngu-0.7V ±0.5% (ejwayelekile).
6. Kanye okokufaka nokuphumayo voltagama-es asungulwe kahle, lungisa ivolumu yokufakatage phakathi kuka-6V kuya ku-14V ubukhulu kanye nesamba somthwalo wamanje ngaphakathi kwebanga lokusebenza le-0A ukuya ku-125A max. Bheka umthamo wokukhiphayotage regulation, okukhiphayo voltagama-ripples, ukushintsha i-waveform ye-node, ukusabela kwesikhashana kokulayisha, namanye amapharamitha. Bheka Umfanekiso 3 ukuze uthole umthamo ofanele wokukhiphatagukulinganisa kwe-ripple.
Ukulinganisa okokufaka/okuphumayo voltagama-ripples ngendlela efanele, ungasebenzisi umthofu omude ku-oscilloscope probe. Bheka Umfanekiso 3 ukuze uthole inqubo efanele ye-scope probe. Imikhondo emifushane, eqinile idinga ukuthengiswa kumatheminali (+) kanye (-) we-input capacitor. Iringi yaphansi ye-probe idinga ukuthinta umthofu (-), futhi ithiphu ye-probe idinga ukuthinta umthofu (+).

Umfanekiso 3. Ukubekwa Kwe-Scope Probe Yokulinganisa Okuphumayo kwe-Ripple Voltage
(Inketho) Ukusebenza nge-VBIAS 7. Iphinikhodi ye-VBIAS iwukukhipha okungu-5.5V kwesilawuli semali yangaphakathi esinganikwa amandla noma sikhutshazwe nge-RUNP. Idatha ye-VBIAS
okokufaka kwesilawuli yiphinikhodi ye-VIN_VBIAS futhi inikwa amandla yi-VIN. I-advantage yokusebenzisa i-VBIAS ukweqa i-INTVCC_LDO yangaphakathi enikwe amandla kusukela ku-VIN, ukuvula iswishi yangaphakathi exhunywe ku-5.5V VBIAS ukuya ku-INTVCC_01 kanye ne-INTVCC_23 yengxenye, ngakho-ke, ukwehlisa ukulahleka kwamandla, ukuthuthukisa ukusebenza kahle kukonke, nokwehlisa ukukhuphuka kwezinga lokushisa kwengxenye uma isebenza ku-VIN ephezulu kanye nefrikhwensi yokushintsha ephezulu. I-VBIAS kufanele yeqe u-4.8V, futhi i-VIN kufanele ibe nkulu kuno-7V ukuze uvule iswishi yangaphakathi exhuma i-VBIAS ku-INTVCC_01 kanye ne-INTVCC_23 yengxenye. Kuzinhlelo zokusebenza ezijwayelekile, kuyanconywa ukuthi i-VBIAS inikwe amandla.
Ukusebenza ku-VIN Ephansi: 4.5V VIN 5.75V 8. Khipha i-R31 ukuze unqamule i-VIN_VBIAS ku-VIN. Susa i-C25. Setha i-RUNP (P1) endaweni ethi OFF. Bophela i-SVIN_01 ku
INTVCC_01 ngokufaka u-R142 nge-resistor engu-0. Bopha i-SVIN_23 ku-INTVCC_23 ngokuhlohla u-R143 nge-resistor engu-0. Qiniseka ukuthi i-VIN ingaphakathi kwe-4.5V VIN 5.75V. Ama-capacitor e-electrolytic angeziwe angase afakwe phakathi kwe-VIN (TP9) ne-GND (TP10) ukuze kuvinjelwe i-VIN ukuthi igwebe noma idubule ibe yivolumu.tage izinga elingadlula i-VIN encane eshiwo (4.5V) kanye ne-VIN ephezulu (5.75V) phakathi nomthamo omkhulu ophumayo wesikhashana.

(Inketho) Isekhethi Yesinyathelo Sokulayisha Ebhodini
9. Ibhodi lokuhlola le-EVAL-LTM4682-A2Z linikeza isekethe yesikhashana yomthwalo osebhodini ukukala ukuchezuka kwe-VOUT peak-topak ngesikhathi somthwalo oguquguqukayo okhuphukayo noma owehlayo. Isifunda sesinyathelo sokulayisha esilula siqukethe ama-MOSFET amabili ahambisanayo we-40V N-channel ochungechungeni olunama-10m amabili ahambisanayo, i-2W, i-1% yezinzwa zamanje. Ama-MOSFET acushwe njenge-voltage ukulawula umthombo wamanje (VCCS) amadivayisi; ngakho-ke, isinyathelo samanje esiphumayo kanye nobukhulu baso zidalwe futhi zilawulwa ngokulungisa ampumthamo wokufakwayo okusetshenzisiwetagngingena esangweni lama-MOSFET. Ijeneretha yomsebenzi inikeza ivolumutagi-pulse phakathi kwe-IOSTEP_CLK01 (TP22) ne-GND (TP2). I-voltagI-e pulse kufanele isethwe kububanzi be-pulse obungaphansi kwama-300µs kanye nomjikelezo womsebenzi omkhulu ongaphansi kuka-2% ukuze kugwenywe ukucindezelwa okushisayo okudlulele kumadivayisi e-MOSFET. Isinyathelo samanje esiphumayo silinganiswa ngokuqondile kuzinqamuli zenzwa zamanje futhi siqashwe ngokuxhuma intambo ye-BNC ukusuka ku-IOSTEP_01 (J1) kuya kokokufaka kwe-oscilloscope (isilinganiso se-scope probe 1:1, DC-coupling). Umthamo ofanayotage esikalini samanje ngu-5mV/1A. Isinyathelo sokulayisha izinga lokubulala lamanje di/dt lingahluka ngokulungisa isikhathi sokukhuphuka nesikhathi sokuwa sevolthi yokufakatage pulse. Isekhethi yesinyathelo sokulayisha ixhunywe ku-VOUT0 ngokuzenzakalelayo. Bona isigaba se-Schematics ukuze uthole imininingwane eyengeziwe. Okukhiphayo ripple voltage kanye nomthamo wokukhiphatage ngesikhathi somthwalo odlulayo ukalwa ku-CO37; i-1x scope probe kanye nojeke wokuhlola kufanele kusetshenziswe. Umthamo wokukhipha we-DCtage kufanele ikalwe phakathi kwe-VOUT0+ (TP16) ne-VOUT0- (TP17).
