Buku la Demo DC1900A ndi bolodi lopangidwa kuti liwunikire momwe gawo la LTM4644EY Quad 4A Limatulutsa Pansi Pansi. Imakhala ndi ma capacitor ochepa olowetsa ndi kutulutsa ndipo imapereka mphamvu yamagetsitage kutsatira kudzera pa TRACK/SS pin kuti atsatire njanji. Bungweli limathandiziranso kulumikizana kwa wotchi yakunja kudzera pa pini ya CLKIN. Tsamba la deta la LTM4644 liyenera kuwerengedwa molumikizana ndi buku lachiwonetseroli musanagwiritse ntchito kapena kusintha gawo lachiwonetsero.
Zogulitsa Malangizo Ogwiritsira Ntchito:
Zotsatirazi ndi malangizo a sitepe ndi sitepe ogwiritsira ntchito Demo Manual DC1900A: 1. Njira Yoyambira Mwamsanga: a. Ikani zodumpha (JP1-JP8) pamalo otsatirawa: - JP1: RUN1 ON - JP2: RUN2 ON - JP3: RUN3 ON - JP4: RUN4 ON - JP8: MODE1 CCM - JP7: MODE2 CCM - JP6: MODE3 CCM - JP5 : MODE4 CCM b. Musanalumikize katundu aliyense, konzani zolowetsamo voltage amapereka pakati pa 4.5V mpaka 14V ndikuyika mafunde a katundu ku 0A. c. Lumikizani katunduyo, voltage supply, ndi mamita monga momwe zikusonyezera Chithunzi 1 cha bukhu la ogwiritsa ntchito. 2. Kusintha Katundu: a. Yatsani kuzungulira. b. Sinthani mafunde olemetsa gawo lililonse mkati mwa 0A mpaka 4A. c. Yang'anani malamulo a katundu, mphamvu, ndi zina. 3. Kuchulukitsidwa Kwakatundu Wopepuka: a. Kuti muwone kuchulukira kopepuka, ikani chodumphira cha Mode pin (JP5-JP8) pamalo a DCM Mode.
Zindikirani:
Malo osasankha odumphira akupezeka pa DC1900A kuti aunikire magwiridwe antchito a LTM4644. Kuti mugwire ntchito yofananira pazotulutsa zonse 4, musayike zodumpha zilizonse za R32-R46. Chonde onani bukhu la ogwiritsa ntchito kuti mudziwe zambiri komanso zojambula zamagawo.

Kufotokozera
Chiwonetsero cha dera la 1900A chimakhala ndi LTM®4644EY μModule® regulator, chowongolera chapamwamba chapamwamba cha quad output step-down regulator. Mtengo wa LTM4644EYtage osiyanasiyana 4V mpaka 14V ndipo amatha kupereka mpaka 4A ya zotulutsa pano pagawo lililonse.
Voliyumu iliyonse yotulutsatage ndi programmable kuchokera 0.6V kuti 5.5V.
LTM4644EY ndi DC/DC point of load regulator mu phukusi la 9mm × 15mm × 5.01mm BGA lomwe limafunikira ma capacitor ochepa chabe olowera ndi kutulutsa. Kutulutsa voltage tracking ikupezeka kudzera pa TRACK/SS pin potsata njanji.
Kulumikizana kwa wotchi yakunja kumapezekanso kudzera pa pini ya CLKIN. Tsamba la deta la LTM4644 liyenera kuwerengedwa molumikizana ndi buku lachiwonetseroli musanagwiritse ntchito kapena kusintha demo circuit 1900A.

Khazikitsanitu mafunde a katundu kukhala 0A.
- Ndi mphamvu yozimitsa, gwirizanitsani katundu, voltage supply ndi mita monga zikuwonetsedwa Chithunzi 1.
- Yatsani magetsi olowera. Zotsatira za voltagma e mita pagawo lililonse akuyenera kuwonetsa voliyumu yomwe yakonzedwatage mkati ± 2%.
- Kamodzi koyenera linanena bungwe voltage imakhazikitsidwa, sinthani mafunde olemetsa pagawo lililonse mkati mwa 0A mpaka 4A ndikuwona kayendetsedwe ka katundu, magwiridwe antchito, ndi magawo ena.
- Kuti muwone kuchulukira kopepuka, ikani Mode pin jumper (JP5-JP8) pamalo a DCM Mode.
Zindikirani: Malo osasankha odumphira akupezeka pa DC1900A kulola kukhazikitsidwa kosavuta kuti awone momwe LTM4644 ikuyendera. Za example, kufananiza zotuluka zonse 4 za LTM4644 palimodzi zinthu 0Ω jumpers kwa R32-R46.
