♠ 2 A, 1.5 MHz PWM chowongolera chotsikira pansi chokhala ndi kukonzanso kogwirizana
ST1S09 ndi chosinthira chotsika cha DC-DC chokometsedwa kuti chizitha kugwiritsa ntchito magetsi otsika.Imapereka mphamvu yapano yopitilira 2 A pamagetsi olowera kuchokera pa 2.7 V mpaka 6 V.
Ma frequency apamwamba a PWM (1.5 MHz) amalola kugwiritsa ntchito tinthu tating'onoting'ono tomwe timakwera pamwamba.
Kuphatikiza apo, popeza cholumikizira chofunikira cholumikizira chikuphatikizidwa, kuchuluka kwa zigawo zakunja kumachepetsedwa kukhala zochepa: chogawanitsa chopinga, inductor ndi ma capacitor awiri.ThePower Good ntchito imayang'anira mosalekeza mphamvu yamagetsi.Mbendera yotseguka ya Power Good imatulutsidwa pamene mphamvu yotulutsa ili mkati mwadongosolo.Komanso, otsika linanena bungwe ripple ndikutsimikiziridwa ndi mawonekedwe amakono a PWM topology komanso kugwiritsa ntchito ma capacitor a ceramic otsika a ESR SMD.Chipangizocho chimatetezedwa ndi kutentha ndipo mphamvu yotulutsa imakhala yochepa kuti isawonongekekupita kufupi mwangozi.ST1S09 ikupezeka mu phukusi la DFN6 (3 x 3 mm).
■ 1.5 MHz yokhazikika pafupipafupi PWM yokhala ndi panomode control
■ 2 A linanena bungwe luso panopa
■ Kuchita bwino kwambiri: > 90%
■ 2 % DC linanena bungwe voteji kulolerana
■ Mabaibulo awiri omwe alipo: mphamvu zabwino kapena zolepheretsa
■ Integrated output over-voltage protection
■ Kusasintha kwa quiescent current: (typ) 1.5 mApa kutentha osiyanasiyana
■ RDSON (mtundu) 100 mΩ
■ Amagwiritsa ntchito ma capacitor ndi ma inductors
■ Kutentha kolowera panjira.-30 ° C mpaka 125 ° C
■ Imapezeka mu DFN6 (3 x 3 mm) pad yowonekera
