♠ TPS51396A 4.5-V rau 24-V, 8-A Synchronous Kauj Ruam-Down Voltage Regulator nrog ULQ ™ Hom rau Ntxiv Roj Teeb Lub Neej
Lub TPS51396A yog tus nqi tsim nyog, cov khoom siv hluav taws xob siab, kev ua haujlwm siab synchronous puck converter nrog kev sib xyaw FETs.
Qhov tseem ceeb ntawm TPS51396A yog nws ULQ (Ultra Low Quiescent) feature los pab kom tsis tshua muaj kev tsis ncaj ncees tam sim no thiab ua haujlwm loj. ULQ feature yog qhov muaj txiaj ntsig zoo rau lub neej ntev roj teeb hauv kev ua haujlwm qis zog. TPS51396A ua haujlwm nrog cov khoom siv hluav taws xob sib txawv ntawm 4.5 V mus rau 24 V. Nws siv DCAP3 kev tswj hom los muab cov lus teb ceev ceev, cov kab zoo, kev tswj hwm, tsis tas yuav tsum tau them nyiaj rau sab nraud, thiab txhawb qis sib npaug series tsis kam (ESR) cov khoom siv hluav taws xob xws li cov khoom tshwj xeeb polymer thiab ultra-low ESR ceramic capacitors.
TPS51396A muab kev tiv thaiv ua tiav OVP, UVP, OCP, OTP, thiab UVLO. Nws yog ua ke lub zog zoo teeb liab thiab tso zis muaj nuj nqi.
MODE tus pin hauv TPS51396A tuaj yeem siv los teeb tsa Eco-Mode lossis OOA hom rau lub teeb ua haujlwm. Eco-Mode tswj kev ua haujlwm siab thaum lub teeb ua haujlwm, thiab OOA hom kev ua haujlwm nrog kev hloov zaus loj dua 25 kHz txawm tias tsis muaj kev thauj khoom.
Lub TPS51396A txhawb nqa ob qho tib si sab hauv thiab sab nraud soft-start time option. Nws muaj lub sijhawm nruab nrab ntawm lub sijhawm pib ntawm 1.3 ms. Yog tias daim ntawv thov xav tau lub sijhawm pib muag ntev dua, tus pin SS sab nraud tuaj yeem siv los ua kom tiav nws los ntawm kev sib txuas rau sab nraud capacitor.
TPS51396A muaj nyob rau hauv 20-pin 3.0-mm × 3.0-mm HotRod pob thiab qhov sib txuas kub tau teev los ntawm -40 ° C txog 125 ° C.
