3 Sharaxaada
TPS65251 waxa uu leeyahay saddex ballaadhan oo isku-dhafan
wax gelinta kala duwan ee wax-ku-oolnimada sare ee beddelayaasha.The
beddelayaasha waxaa loogu talagalay inay fududeeyaan codsigeeda
iyadoo la siinayo naqshadeeyaha ikhtiyaarka ah inuu hagaajiyo
isticmaalka si waafaqsan codsiga la beegsaday.
Beddelayaashu waxay ku shaqayn karaan 5-, 9-, 12- ama 15-V
nidaamyada waxayna leeyihiin transistors awood isku dhafan.The
danab wax soo saarka waxaa lagu dejin karaa dibadda iyadoo la isticmaalayo resistor ah
kala qaybiya qiime kasta oo u dhexeeya 0.8 V oo u dhow
sahayda gelin.Beddel kastaa wuxuu sifeeyaa pin kaas
waxay ogolaataa dib u dhac bilawga ujeedooyinka isku xigxiga,
biin jilicsan oo u oggolaanaya waqtiga bilawga jilicsan ee la hagaajin karo
doorashada capacitor-ka jilicsan, iyo xadka hadda jira
(RLIMx) pin awood u siinaya naqshadeeyaha inuu hagaajiyo hadda
xaddid adiga oo dooranaya iska caabin dibadeed oo aad hagaajiso
doorashada induction.Xakamaynta qaabka hadda jirta waxay ogolaataa a
magdhow RC fudud.
Inta jeer ee beddelka beddelayaashu midkoodna wuu awoodaa
lagu rakibo iska caabin dibadeed oo ku xidhan ROSC
pin ama waxaa la isla meel dhigi karaa saacad dibadda ah
ku xidhan pin SYNC haddii loo baahdo.Beddelka
nidaamiyayaasha waxaa loogu talagalay inay ka shaqeeyaan 300 kHz ilaa
2.2 MHz.180° ka baxsan hawlgalka wejiga u dhexeeya Buck
1 iyo Buck 2, 3 (Buck 2 iyo 3 waxay ku socdaan marxaladda)
waxay yaraynaysaa shuruudaha shaandhaynta galinta
