Kodi Integrated Circuit (IC) ndi chiyani?
Asanatulukire ma IC, njira yayikulu yopangira mabwalo inali kusankha zinthu monga ma diode, ma transistors, resistors, inductors ndi capacitors ndikuzilumikiza ndi mapewa.Koma chifukwa cha kukula ndi zovuta zogwiritsira ntchito mphamvu, kunali koyenera kupanga dera laling'ono lokhala ndi mphamvu zochepa, kudalirika komanso kugwedeza.
Pambuyo pa kupangidwa kwa ma semiconductors ndi ma transistors, zinthu zidasinthidwa pang'ono, koma kukula kwa mabwalo ophatikizika kunasintha nkhope yaukadaulo wamagetsi.Jack Kilby waku Texas Instruments ndi Bob Noyce waku Intel ndi omwe amapanga mabwalo ophatikizika, ndipo adazichita pawokha.
Dera lophatikizika ndi lingaliro lofunikira lamagetsi lomwe limamanga pamalingaliro ena oyambira omwe adakambidwa kale mu silabasi yathu.Chifukwa chake, kuti mufufuze mwachangu, pitani pazolemba zomwe zili pansipa:
Zithunzi za LMR16030
- Zatsopano zomwe zilipo:LM76003 60-V, 3.5-A, 2.2-MHz synchronous converter
- 4.3-V mpaka 60-V zolowetsamo
- 3-A mosalekeza linanena bungwe panopa
- Zotsika kwambiri za 40-µA zikugwira ntchito quiescent current
- 155-mΩ wapamwamba mbali MOSFET
- Ulamuliro wamakono wamakono
- Ma frequency osinthika osinthika kuchokera ku 200 kHz kupita ku 2.5 MHz
- Kulunzanitsa pafupipafupi ku wotchi yakunja
- Malipiro amkati kuti agwiritse ntchito mosavuta
- Kugwira ntchito mozungulira kwapamwamba kumathandizidwa
- Mwatsatanetsatane yambitsani zolowetsa
- 1-µA shutdown current
- Thermal, overvoltage ndi yochepa chitetezo
- 8-pini HSOIC yokhala ndi PowerPAD™ phukusi
- Pangani mapangidwe anu pogwiritsa ntchito LM76003 ndiWEBENCH®Wopanga Mphamvu
- Pangani mapangidwe anu pogwiritsa ntchito LM16030 ndiWEBENCH®Wopanga Mphamvu
Zithunzi za LMR16030
LMR16030 ndi chowongolera chotsika cha 60-V, 3-A SIMPLE SWITCHER chokhala ndi MOSFET yapakatikati.Ndi zolowetsa zambiri kuchokera ku 4.3 V mpaka 60 V, ndizoyenera kugwiritsa ntchito zosiyanasiyana kuchokera ku mafakitale kupita ku magalimoto opangira magetsi kuchokera kumagwero osayendetsedwa.Pakali pano wowongolera ndi 40 µA munjira yogona, yomwe ili yoyenera pamakina oyendetsedwa ndi batire.Kutsika kwambiri kwa 1-µA komwe kumatsekeka kumatha kutalikitsa moyo wa batri.Ma frequency osinthika osinthika amalola kuti magwiridwe antchito kapena kukula kwa gawo lakunja kukwaniritsidwe.Kulipira kwa loop mkati kumatanthauza kuti wogwiritsa ntchito alibe ntchito yotopetsa yakupanga chipukuta misozi.Izi zimachepetsanso zigawo zakunja za chipangizocho.Kuwongolera molondola kumalola kuphweka kwa zowongolera ndi kutsata mphamvu zamakina.Chipangizocho chilinso ndi zida zodzitchinjiriza monga malire apano ndi kuzungulira, kumva kutentha ndi kutsekeka chifukwa cha kutha kwamphamvu kwambiri, komanso chitetezo chamagetsi otulutsa.
LMR16030 imapezeka mu phukusi la 8-pini la HSOIC lokhala ndi pad yowonekera kuti ichepetse kutentha.
Chogulitsa chatsopano, LM76003, chimafuna zigawo zochepa zakunja ndipo chili ndi pinout yopangidwa kuti ikhale yosavuta, yabwino kwambiri ya PCB ya EMI ndi magwiridwe antchito amafuta.Onani tebulo lofananiza la chipangizo kuti mufananize zochulukira.
