♠ GreenChip dual synchronous rectifier maub los
TEA1995T yog thawj cov khoom lag luam ntawm lub cim tshiab ntawm Synchronous Rectifier (SR) maub los ICs rau cov khoom siv hluav taws xob hloov pauv. Nws suav nrog txoj kev hloov kho qhov rooj tsav tsheb rau kev ua haujlwm siab tshaj plaws ntawm txhua qhov kev thauj khoom.
Lub TEA1995T yog ib tug tshwj xeeb maub los IC rau synchronous rectification ntawm ob sab ntawm resonant converters. Nws muaj ob theem tsav tsheb rau kev tsav tsheb SR MOSFETs, uas kho cov txiaj ntsig ntawm lub hauv paus kais theem nrab transformer windings. Ob lub qhov rooj tsav tsheb theem muaj lawv tus kheej sensing inputs thiab ua hauj lwm ntawm nws tus kheej.
Lub TEA1995T kuj tseem siv tau rau hauv ntau qhov tso zis flyback converters nrog SR MOSFET tso rau sab qis.
TEA1995T yog tsim los ntawm Silicon-On-Insulator (SOI) txheej txheem.
2.1 Efficiency nta
• Adaptive rooj vag tsav rau siab tshaj plaws efficiency ntawm tej load
• Muab tam sim no hauv lub zog txuag kev ua haujlwm qis dua 200 μA
2.2 Daim ntawv thov nta
• Dav siv hluav taws xob ntau ntawm 4.5 V txog 38 V
• Dual synchronous rectification rau LLC resonant hauv SO8 pob
• Synchronous rectification rau ntau qhov tso zis flyback converters
• Txhawb nqa 5 V kev ua haujlwm nrog qib logic SR MOSFETs
• Sib txawv inputs rau sensing qhov ntws thiab qhov voltages ntawm txhua SR MOSFET
2.3 Tswj nta
• SR tswj tsis tau yam tsawg kawg nkaus raws sij hawm
• Adaptive gate drive rau ceev tig-tawm thaum kawg ntawm conduction
• UnderVoltage LockOut (UVLO) tiv thaiv nrog lub rooj vag active rub-down
Lub TEA1995T yog npaj rau cov khoom siv hluav taws xob resonant. Nyob rau hauv xws li daim ntaub ntawv, nws muaj peev xwm tsav ob sab nraud synchronous rectifier MOSFETs rau rectification ntawm voltages ntawm ob theem nrab windings ntawm lub transformer. Cov MOSFETs no hloov diodes. Nws tuaj yeem siv rau hauv txhua qhov khoom siv hluav taws xob uas xav tau kev ua haujlwm siab:
• Adapters
• Cov khoom siv fais fab rau desktop PC thiab tag nrho-hauv-ib lub PC
• Cov khoom siv fais fab rau TV
• Cov khoom siv fais fab rau cov servers
