♠ TPS65251 4.5-V ukuya 18-V Igalelo, High-yangoku, Synchronous Inyathelo-Ezantsi iBuck Switcher eZithathu ezineFET eDityanisiweyo.
I-TPS65251 ineenguqu ezintathu ezibanzi ezihambelanayo ezinoluhlu oluphezulu lweziguquli ezisebenzayo.Abaguquli benzelwe ukwenza lula isicelo sabo ngelixa benika umyili ukhetho lokuphucula ukusetyenziswa kwabo ngokwesicelo ekujoliswe kuso.
Abaguquli banokusebenza kwiinkqubo ze-5-, 9-, 12- okanye i-15-V kwaye babe ne-transistors yamandla edibeneyo.I-voltage ephumayo inokusekwa ngaphandle usebenzisa i-resistor divider kulo naliphi na ixabiso phakathi kwe-0.8 V kwaye isondele kwi-input supply.Iimpawu zesiguquli ngasinye zenza iphini elivumela ukulibaziseka kokuqalisa ngeenjongo zolandelelwano, isikhonkwane sokuqalisa esithambileyo esivumela ixesha lokuqalisa elithambileyo ngokukhetha i-capacitor ethambileyo, kunye nomda wangoku (RLIMx) iphini eyenza umyili alungelelanise umda wangoku. ngokukhetha i-resistor yangaphandle kunye nokwandisa ukhetho lwe-inductor.Ulawulo lwemowudi yangoku luvumela imbuyekezo yeRC elula.
I-frequency switching frequency of converters inokuthi ibekwe kunye ne-resistor yangaphandle exhunywe kwi-ROSC pin okanye inokulungelelaniswa kwiwotshi yangaphandle exhunywe kwi-SYNC pin xa ifuneka.Izilawuli zokutshintsha zenzelwe ukusebenza ukusuka kwi-300 kHz ukuya kwi-2.2 MHz.I-180 ° ngaphandle kokusebenza kwesigaba phakathi kweBuck 1 kunye neBuck 2, 3 (I-Buck 2 kunye ne-3 iqhutywe kwisigaba) inciphisa iimfuno zokucoca igalelo.
