♠ TPS5433xA 4.5-V rau 28-V Input, 3-A Output, Synchronous Kauj Ruam DC-DC Converter
TPS5433xA tsev neeg ntawm cov khoom siv yog synchronous converters nrog ib qho input-voltage ntau yam ntawm 4.5 V rau 28 V. Cov khoom siv no suav nrog Cov cuab yeej no muaj kev sib xyaw ua ke qis-sab hloov FET uas tshem tawm qhov xav tau rau sab nraud diode uas txo cov khoom suav.
Kev ua haujlwm tau zoo tshaj plaws los ntawm kev sib xyaw ua ke 128-mΩ thiab 84-mΩ MOSFETs, qis IQ thiab mem tes hla ntawm lub teeb loads. Siv tus pin qhib, kaw qhov tam sim no raug txo rau 2 μA. Cov kauj ruam-down (buck) converter no muab cov kev cai raug rau ntau yam kev thauj khoom nrog kev tswj xyuas qhov hluav taws xob zoo uas yog 1.5% dhau qhov kub.
Cycle-by-cycle tam sim no txwv nyob rau sab siab MOSFET tiv thaiv TPS5433xA tsev neeg ntawm cov khoom siv nyob rau hauv cov xwm txheej dhau los thiab tau txhim kho los ntawm kev txwv qis qis tam sim no uas tiv thaiv kev khiav tawm tam sim no. Qhov qis-sab dab ntxwg nyoog tam sim no-tso tawm qhov qis-sab MOSFET kom tiv thaiv kev thim rov qab ntau dhau. Kev tiv thaiv Hiccup yog tshwm sim yog tias tus mob overcurrent txuas ntxiv mus ntev dua li lub sijhawm teem tseg. Thermal shutdown disables lub cuab yeej thaum kub tuag tshaj qhov pib thiab enables lub ntaus ntawv dua tom qab lub built-in thermal hiccup lub sij hawm.
