Zithunzi za TPS61088RHLR

Kufotokozera mwachidule:

TPS61088 ndi kachulukidwe kamphamvu kwambiri, chosinthira chophatikizika bwino cha synchronous boost chosinthira mphamvu cha 11-mΩ ndi 13-mΩ rectifier switch, yopereka njira zotsogola, zazing'ono zamakina osunthika.TPS61088 ili ndi ma voliyumu osiyanasiyana a 2.7V mpaka 12V kuti athandizire ntchito zoyendetsedwa ndi batire ya cell imodzi kapena ma cell awiri a Li-ion.Chipangizocho chili ndi 10A kusintha mphamvu zamakono ndipo chikhoza kutulutsa ma voltages mpaka 12.6V.

TPS61088 ndi kachulukidwe kamphamvu kwambiri, chosinthira chophatikizika bwino cha synchronous boost chokhala ndi 11-mΩ power switch ndi 13-mΩ rectifier switch kuti ipereke njira yabwino kwambiri komanso yaying'ono pamakina osunthika.TPS61088 ili ndi ma voliyumu ambiri olowera kuchokera ku 2.7 V mpaka 12 V kuthandizira mapulogalamu okhala ndi batire ya cell imodzi kapena ma cell awiri a Lithium.Chipangizocho chili ndi mphamvu ya 10-A yosinthira panopa ndipo imatha kupereka mphamvu yotulutsa mphamvu mpaka 12.6 V. TPS61088 imagwiritsa ntchito zosinthika nthawi zonse zomwe zimagwiritsidwa ntchito panthawiyi kuti zithetse mphamvu zowonongeka.Pazinthu zolemetsa kwambiri, TPS61088 imagwira ntchito mu pulse width modulation (PWM).Pamalo opepuka, chipangizocho chili ndi njira ziwiri zogwirira ntchito zosankhidwa ndi pini ya MODE.

Imodzi ndi mawonekedwe a pulse frequency modulation (PFM) kuti apititse patsogolo magwiridwe antchito ndipo ina imakakamizidwa PWM mode kuti apewe zovuta zamagwiritsidwe ntchito chifukwa cha kutsika kwafupipafupi.Kusintha kwafupipafupi mu PWM mode ndi chosinthika, kuyambira 200 kHz mpaka 2.2 MHz ndi resistor kunja.TPS61088 imagwiritsanso ntchito pulogalamu yoyambira yofewa komanso kusintha kosinthika kosinthira komwe kumagwirira ntchito.Kuphatikiza apo, chipangizochi chimapereka chitetezo chowonjezera cha 13.2-V, chitetezo chamkombero ndi mkombero, komanso chitetezo chotseka chamoto.TPS61088 ikupezeka mu phukusi la 4.50-mm × 3.50-mm 20-pini VQFN.
