Igice Ibisobanuro kuri TPS61088RHLR

ibisobanuro bigufi:

TPS61088 nubucucike bukabije, bwuzuye bwuzuye bwa syncronous boost ihindura hamwe na 11-mΩ ya power na 13-mΩ ikosora, itanga igisubizo cyiza cyane, gito-gito kuri sisitemu yikuramo.TPS61088 ifite amashanyarazi yagutse ya 2.7V kugeza 12V kugirango ashyigikire porogaramu ikoreshwa na bateri imwe cyangwa selile ebyiri Li-ion.Igikoresho gifite ubushobozi bwa 10A bwo guhindura ibintu kandi burashobora gutanga amashanyarazi agera kuri 12.6V.

Ibisobanuro

TPS61088 nubucucike bwimbaraga nyinshi, bwuzuzanya bwuzuye bwoguhindura imbaraga hamwe na 11-mΩ ya power na 13-mΩ ikosora kugirango itange imikorere ihanitse kandi nini nini muri sisitemu yimukanwa.TPS61088 ifite intera nini yinjiza ya voltage kuva kuri 2.7 V kugeza 12 V kugirango ishyigikire porogaramu hamwe na bateri ya Litiyumu imwe.Igikoresho gifite 10-Guhindura ubushobozi bwubu kandi burashobora gutanga amashanyarazi asohoka kugeza kuri 12.6 V. TPS61088 ikoresha imiterere ihindagurika yigihe kitari gito cyigihe cyo kugenzura topologiya kugirango igenzure ingufu zisohoka.Mugihe kiremereye kandi kiremereye, TPS61088 ikora muburyo bwa pulse ubugari (PWM).Muburyo bworoshye bwo gutwara ibintu, igikoresho gifite uburyo bubiri bwo gukora bwatoranijwe na MODE pin.

Imwe ni uburyo bwa pulse frequency modulation (PFM) uburyo bwo kunoza imikorere naho ubundi ihatirwa uburyo bwa PWM kugirango wirinde ibibazo byatewe no guhinduranya inshuro nke.Guhindura inshuro muburyo bwa PWM birashobora guhinduka, kuva kuri 200 kHz kugeza kuri 2.2 MHz na rezistor yo hanze.TPS61088 nayo ishyira mubikorwa porogaramu ishobora kworoha-gutangira ibikorwa hamwe noguhindura impinduramatwara igezweho.Mubyongeyeho, igikoresho gitanga 13.2-V ibisohoka birinda ingufu zirenze urugero, kurinda byikurikiranya kurinda, hamwe no kurinda umuriro.TPS61088 iraboneka muri 4.50-mm × 3.50-mm 20-pin ya VQFN.
