Ubushushu bokusebenza kwi-Ambient
-Isixhobo seHBM ESD iNqanaba lesi-2
– Isixhobo CDM ESD Classification Level C4B
3.I-Voltage yegalelo: 4 V–40 V (45 V Abs. Max.)
I-4.I-Output Voltage: 4 V–75 V (80 V Abs. Max.)
5.Fixed-Frequency Current-Mode Controller Nge
Imbuyekezo ye-Slope edibeneyo
6.Izirhintyi zoMmiselo eziMbini, iSiphumo esiQoqoyo-Esikhoyo
kunye ne-Constant-Voltage Output yeChannel nganye
7.High-Side Uluvo lwangoku:
– 150-mV okanye 300-mV Sense Voltage (EEPROM
Ukhetho)
– ±6-mV Offset (Ukufikelela malunga ne-4% okanye 2%
Ukuchaneka kwangoku kwe-LED)
I-8.I-Output Voltage Sense, i-Voltage yangaphakathi
Isalathiso: 2.2 V ±5%
9.I-Integrated Low-Side NMOS-FET Driver: Incopho
Isango-Qhuba isiHlobo sangoku.0.7 A
10.Ungqamaniso lwamaxesha ngamaxesha
11.Zombini i-PWM Dimming kunye ne-Analog Dimming
12. Uxilongo:
– High-Side yangoku (LED yangoku) Ifumaneka njenge
Isiphumo seAnalog
-Vula-i-LED kunye neMfutshane ukuya kwi-GND yokuFumana
– Ukhuseleko lweZiphumo olufutshane
13.Ngaphakathi Ngaphakathi- kunye ne-Overtage Lockout
Usetyenziso
I-Automotive Headlight LED Driver
Ukukhanya okuphezulu kwezicelo ze-LED
Inkcazo
Usapho lwezixhobo ze-TPS9260x-Q1 sisijelo esinye kunye ne-LED yangoku enecala elinecala eliphezulu.
umqhubi.Ngokhuseleko olupheleleyo kunye noxilongo, olu sapho lwezixhobo lunikezelwe kwaye lufaneleke ngokufanelekileyo kwizibane zangaphambili zemoto.Isiseko somqhubi ngamnye ozimeleyo yi-peak-current-mode boost controller.Umlawuli ngamnye unee-loops ezimbini ezizimeleyo zeempendulo, i-loop-feedback loop ene-highside current-sensing shunt kunye ne-voltage-feedback loop ene-external resistor-divider network.Umlawuli uhambisa i-voltage ephuma rhoqo okanye i-aconstant output current.Umthwalo oqhagamshelweyo unquma ukuba isixhobo silawula umbane ophuma rhoqo (ukuba isekethe ifikelela kwindawo yokumisela yangoku ngaphambi kokuba i-voltage isete-point) okanye i-voltage ephuma rhoqo (ukuba isekethe ifikelela kwindawo yokubeka umbane ifike kuqala, umzekelo, kwindawo evulekileyo. -imeko yomthwalo).Umlawuli ngamnye uxhasa zonke iitopologi eziqhelekileyo ezifana ne-boost, i-boost-to-battery, i-SEPIC, okanye i-flyback.Usetyenziso lwecala eliphezulu lomqhubi we-PMOS FET zenzelwe ukufiphala kwePWM kumtya we-LED kunye nokunqunyulwa kwimeko emfutshane yangaphandle. isekethe ukuya kwi-GND ukukhusela isekethe.IiNkcukacha zeSixhobo(1)ICANDELO INOMBOLO INGXELO-VOLTAGE
