Kev piav qhia rau TPS53219A
Lub TPS53219A ntaus ntawv yog ib qho me me ib qho khoom siv phaw nrog kev hloov kho ON-time D-CAPmode tswj.Cov cuab yeej tsim nyog rau cov zis hluav taws xob tsawg, siab tam sim no, PC system fais fab kev tsheb ciav hlau thiab cov khoom siv hluav taws xob zoo sib xws (POL) hauv cov khoom siv digital.Cov pob me me thiab tsawg tus pin-suav txuag qhov chaw ntawm PCB, thaum lub siab EN tus pin thiab pre-set frequencyselections simplifies lub hwj chim mov tsim.Txoj kev hla ntawm lub teeb load, muaj zog gatedrivers, thiab sab qis FET RDS (ntawm)tam sim no sensing txhawb qis-tsawg thiab highefficiency, tshaj ib tug dav load ntau yam.Kev hloov pauv input voltage (high-sab FET ntws voltage) ntau yog nyob nruab nrab ntawm 4.5 V thiab 25 V, thiab cov zis voltage ntau ntawm 0.6 V thiab 5.5 V. TheTPS53219A muaj nyob rau hauv 16-pin, QFN pob teev los ntawm -40 ° C rau +85 ° C.
