DESCRIPTION
2
• Ama-MOSFET amabili angu-45-mΩ (okujwayelekile) Okuphakeme
Idivayisi ye-TPS54319 iyi-6 V egcwele, 3 A,
Ukusebenza kahle emithwalweni engu-3-A
i-synchronous step down isiguquli semodi yamanje nge
ama-MOSFET amabili ahlanganisiwe.
•
300kHz ukuya ku-2MHz Imvamisa Yokushintsha
•
0.8 V ± 3.0% Voltage Reference Over
I-TPS54319 inika amandla imiklamo emincane ngokuhlanganisa
ama-MOSFET, esebenzisa ukulawula kwemodi yamanje ukuze
Izinga lokushisa (0°C ukuya ku-85°C)
nciphisa isibalo sengxenye yangaphandle, ukunciphisa i-inductor
•
Ivumelanisa Newashi Langaphandle
usayizi ngokunika amandla kufika ku-2 MHz ukushintsha imvamisa,
•
Isiqalo Esinensayo Esilungisekayo/Ukulandelanisa
kanye nokunciphisa unyawo lwe-IC nge-3mm x encane
•
I-UV ne-OV Power Output Okuhle
3mm iphakheji ye-QFN ethuthukiswe ngokushisa.
•
-40°C kuya ku-150°C I-Operating Junction
I-TPS54319 inikeza ukulawulwa okunembile kwe-a
Izinga Lokushisa
imithwalo ehlukahlukene eneVoltage enembile engu-±3.0%.
Ireferensi (VREF) phezu kwezinga lokushisa.
•
Ithuthukiswe Ngokushisa 3mm × 3mm 16-pin QFN
•
Iphinikhodi ihambisana ne-TPS54318
Ukusebenza kahle kukhuliswa nge-45mΩ ehlanganisiwe
Ama-MOSFET kanye ne-360mA ejwayelekile yokunikezwa kwamanje.Ukusebenzisa
iphinikhodi yokunika amandla, amandla okunikezwayo okuvala shaqa kwehliselwe ku
IZICELO
2 µA ngokufaka imodi yokuvala shaqa.
•
I-Low-Voltage, I-High-Density Power Systems
•
I-point-of-load Regulation for Consumer
Ngaphansi kwe-voltage lockout isethwe ngaphakathi ku-2.6 V, kodwa
Izinhlelo zokusebenza ezifana ne-Set Top Boxes, i-LCD
inganyuswa ngokuhlela umkhawulo nge
Izibonisi, CPE Equipment
inethiwekhi ye-resistor kuphini lokunika amandla.Okukhiphayo
Irempu yokuqalisa i-voltage ilawulwa ukuqala kancane
phini.Isignali enhle yamandla okukhipha amanzi ikhombisa i
UHLELO OLULULA
okukhiphayo kungaphakathi kuka-93% kuya ku-107% wevoltheji yayo yokulinganisa.
i-spacer esime mpo
Ukugoqa imvamisa emuva futhi ukuvala shaqa okushisayo kuvikela
i-spacer esime mpo
idivayisi ngesikhathi sesimo esingaphezu kwamanje.
I-TPS54319 isekelwa ku-SwitcherPro™
