♠ TPS51396A 4.5-V ukuya 24-V, 8-A Synchronous Step-Down phantsi Voltage Regulator kunye ULQ™ Imowulo kuBomi bebhetri eyandisiweyo
I-TPS51396A yindleko esebenzayo, igalelo le-voltage ephezulu, i-high-efficiency synchronous buck converter kunye nee-FET ezidibeneyo.
Into ephambili ye-TPS51396A yi-ULQ yayo (i-Ultra Low Quiscent) eyenza ukuba i-low-bias isebenze ngoku kunye nomsebenzi omkhulu. Isici se-ULQ siluncedo kakhulu kubomi bebhetri obude ekusebenzeni kwamandla aphantsi. I-TPS51396A isebenza nge-voltage yegalelo lokubonelela ukusuka kwi-4.5 V ukuya kwi-24 V. Isebenzisa imodi yokulawula i-DCAP3 ukubonelela ngempendulo ekhawulezayo yexeshana, umgca olungileyo, ukulawulwa komthwalo, akukho mfuneko yembuyekezo yangaphandle, kwaye ixhasa i-serial equivalent series resistance (ESR) i-capacitors ephumayo efana ne-specialty polymer kunye ne-ultra-low caramic ESR.
I-TPS51396A ibonelela ngokhuseleko olupheleleyo lwe-OVP, i-UVP, i-OCP, i-OTP, kunye ne-UVLO. Idityaniswe amandla isignali elungileyo kunye nomsebenzi wokukhupha imveliso.
I-MODE pin kwi-TPS51396A ingasetyenziselwa ukuseta i-Eco-Mode okanye i-OOA mode yokusebenza komthwalo okhanyayo. I-Eco-Mode igcina ukusebenza kakuhle okuphezulu ngexesha lokusebenza komthwalo wokukhanya, kunye nokusebenza kwemowudi ye-OOA kunye nokutshintsha okuphindaphindiweyo okukhulu kune-25 kHz nokuba akukho kulayisha.
I-TPS51396A ixhasa ukhetho lwangaphakathi nangaphandle lwexesha lokuqalisa elithambileyo. Inexesha langaphakathi elimisiweyo lokuqala elithambileyo le-1.3 ms. Ukuba isicelo sidinga ixesha elide lokuqala elithambileyo, i-pin ye-SS yangaphandle ingasetyenziselwa ukufezekisa ngokudibanisa i-capacitor yangaphandle.
I-TPS51396A ifumaneka kwi-20-pin 3.0- mm × 3.0-mm iphakheji ye-HotRod kunye nobushushu be-junction buchazwe ukusuka -40 ° C ukuya kwi-125 ° C.
