Apejuwe
Circuit ifihan 2110A jẹ oluyipada igbesẹ-isalẹ monolithic ti o nfihan LT®8631. Igbimọ demo jẹ apẹrẹ fun iṣelọpọ 5V lati titẹ sii 6.5V si 100V ni igbohunsafẹfẹ iyipada 400kHz. Iwọn titẹ sii jakejado jẹ ki o dara fun ṣiṣakoso agbara lati ọpọlọpọ awọn orisun lọpọlọpọ, pẹlu-ọkọ ayọkẹlẹ, awọn ọna ṣiṣe ile-iṣẹ ati awọn ipese tẹlifoonu. LT8631 jẹ iwapọ kan, ṣiṣe giga amuṣiṣẹpọ monolithic igbese-isalẹ olutọsọna iyipada. Yipada agbara, isanpada ati awọn iyika pataki miiran wa ninu LT8631 lati dinku awọn paati ita ati irọrun apẹrẹ. Igbohunsafẹfẹ iyipada LT8631 le ṣe eto boya nipasẹ resistor oscillator tabi aago ita lori iwọn 100kHz si 1MHz. PIN SYNC ti o wa lori igbimọ demo ti wa ni ilẹ (JP1 ni ipo Burst®) nipasẹ aiyipada fun iṣẹ kekere ripple Burst Mode. Lati muṣiṣẹpọ si aago ita, gbe JP1 si SYNC ki o lo aago ita si SYNC turret. Ti o ba nilo iṣẹ-fifo-ọpọlọ, gbe JP1 si ipo igbohunsafẹfẹ ti o wa titi. Nọmba 1 fihan ṣiṣe ti Circuit ni titẹ sii 12V ni yiyan Ipo Burst. Igbimọ demo ti fi àlẹmọ EMI sori ẹrọ.

Circuit ifihan 2110A rọrun lati ṣeto lati ṣe iṣiro-jẹ iṣẹ ti LT8631. Tọkasi Nọmba 3 fun iṣeto ohun elo wiwọn to dara ati tẹle ilana ni isalẹ:
AKIYESI. Nigba idiwon igbewọle tabi o wu voltage ripple, itọju gbọdọ wa ni ya lati yago fun a gun ilẹ asiwaju lori oscilloscope ibere. Ṣe iwọn titẹ sii tabi igbejade voltage ripple nipa fifọwọkan sample ibere taara kọja awọn VIN tabi VOUT ati GND ebute. Wo olusin 4 fun ilana iwọn to dara.
- Gbe JP1 sori ipo GND.
- Pẹlu pipa agbara, so ipese agbara titẹ sii pọ si VEMI ati GND. Ti iṣẹ EMI/EMC ko ba ṣe pataki, àlẹmọ EMI igbewọle le ti kọja nipasẹ sisopọ ipese agbara igbewọle si VIN ati GND.
- Pẹlu agbara pipa, so awọn ẹru pọ lati VOUT si GND.
