♠ TPS65251 4.5-V rau 18-V Input, High-Tam sim no, Synchronous Kauj ruam-Down Peb Buck Switcher Nrog Integrated FET
Lub TPS65251 nta peb synchronous wide input range high efficiency phaw converters. Cov converters tau tsim los ua kom yooj yim rau nws daim ntawv thov thaum muab tus tsim qauv xaiv los ua kom zoo dua lawv cov kev siv raws li lub hom phiaj daim ntawv thov.
Cov converters tuaj yeem ua haujlwm hauv 5-, 9-, 12- lossis 15-V systems thiab muaj kev sib xyaw fais fab transistors. Cov zis hluav taws xob tuaj yeem raug teeb tsa sab nraud siv lub resistor divider rau txhua tus nqi ntawm 0.8 V thiab ze rau cov khoom siv. Txhua lub converter nta ua kom tus pin uas tso cai rau ncua sij hawm pib rau lub hom phiaj sib txuas, tus pin muag muag uas tso cai rau lub sijhawm pib soft-start los ntawm kev xaiv lub soft-start capacitor, thiab qhov txwv tam sim no (RLIMx) tus pin uas tso cai rau tus tsim los kho qhov txwv tam sim no los ntawm kev xaiv ib qho kev tiv thaiv sab nraud thiab optimize qhov kev xaiv ntawm inductor. Kev tswj hom tam sim no tso cai rau kev them nyiaj RC yooj yim.
Kev hloov zaus ntawm cov hloov pauv tuaj yeem raug teeb tsa nrog tus tiv thaiv sab nraud txuas nrog ROSC tus pin lossis tuaj yeem synchronized rau lub moos sab nraud txuas nrog SYNC tus pin yog xav tau. Cov kev hloov pauv hloov tau tsim los ua haujlwm ntawm 300 kHz txog 2.2 MHz. 180 ° tawm ntawm lub sijhawm ua haujlwm ntawm Buck 1 thiab Buck 2, 3 (Buck 2 thiab 3 khiav hauv theem) txo qis cov kev xav tau lim tawm.
