♠ LTC1474/LTC1475 Low Quiscent Pakali pano Zosintha Zotsika Kwambiri
Chithunzi cha LTC®1474/LTC1475 mndandanda ndi osinthira otsika kwambiri omwe ali ndi mphamvu yamkati ya P-channel MOSFETmasiwichi omwe amangojambula 10µA wamba wa DC omwe amapereka pakali panopalibe katundu pamene kusunga linanena bungwe voteji. Chithunzi cha LTC1474imagwiritsa ntchito kutseka koyendetsedwa ndi malingaliro pomwe LTC1475 imakhala ndi batani lotsegula / kuzimitsa.
Kuchepa kwaposachedwa kophatikizana ndi ntchito ya Burst Mode TM kumathandizira LTC1474/LTC1475 kukhalabe yogwira ntchito bwino pa katundu wambiri. Zinthu izi, nazonsondi kuthekera kwawo kwa 100% ntchito yozungulira yosiyira otsikandi mitundu yosiyanasiyana yolowera, pangani LTC1474/LTC1475yabwino pakali pano (mpaka 300mA) yoyendetsedwa ndi batiremapulogalamu.
Peak switch panopa ndi wosuta-programmable ndichosankhira sensor sensor (zosasintha kukhala 325mA osachepera ngati sichonchoused) kupereka njira yosavuta yokwaniritsira kapangidwe kakekwa mapulogalamu ochepera apano. Pachimake panopa ulamuliroimaperekanso chitetezo chachifupi komanso machitidwe abwino oyambira. Chowunikira chochepa cha batri chomwe chimagwirabe ntchitomu shutdown imaperekedwa.
Kupezeka kwa LTC1474/LTC1475 mu 8-lead MSOPndi phukusi la SO ndikufunika zowonjezera zowonjezeraperekani njira yochepetsera madera.
