♠ Triple Step-Down Switching Regulator nrog 100% Lub Luag Haujlwm Ua Haujlwm
Lub LT® 3514 muaj peb lub regulators (2A, 1A, 1A tso zis tam sim no). Cov cuab yeej muaj kev ua haujlwm dav dav ntawm 3.2V txog 36V. Ib qho on-chip boost regulator tso cai rau txhua tus channel ua haujlwm txog 100% lub luag haujlwm. LT3514 yog tsim los txo qis cov khoom siv sab nraud suav thiab ua rau ib qho yooj yim thiab me me daim ntawv thov Circuit Court.
LT3514 ua haujlwm zoo hauv cov xwm txheej tsis raug. Cycle by-cycle peak tam sim no txwv thiab ntes diode tam sim no txwv qhov ntsuas tiv thaiv IC thaum muaj xwm txheej dhau. Ther-mal kaw tiv thaiv lub hwj chim hloov ntawm qhov kub siab. Soft-start pab tswj lub ncov inductor tam sim no thaum pib.
Lub LT3514 kuj tseem muaj qhov tso zis hluav taws xob taug qab thiab sib sau ua ke, programmable zaus, programmable undervoltage lockout, thiab lub hwj chim zoo tus pin los qhia thaum txhua qhov kev tso tawm nyob rau hauv kev cai.
LT3514 muaj ib qho tsawg dua channel (CH2) dua li LT3504, thiab muaj ib channel (CH3) uas tso tawm 2A hloov 1A. LT3514 hauv QFN yog tus pin sib xws nrog LT3504. LT3504 muab plaub 1A tso zis
• Wide Input Voltage Range: 3.2V rau 36V (40V Transient)
