♠ I-Triple Step-Down Switching Regulator ene-100% yoMsebenzi woMjikelo wokuSebenza
I-LT®3514 iqulethwe ngabalawuli abathathu (2A, 1A, 1A output current). Isixhobo sinoluhlu olubanzi lwegalelo lokusebenza lwe-3.2V ukuya kwi-36V. I-on-chip boost regulator ivumela itshaneli nganye ukuba isebenze ukuya kuthi ga kwi-100% yomjikelo womsebenzi. I-LT3514 yenzelwe ukunciphisa ukubalwa kwecandelo langaphandle kunye neziphumo kwisekethe yesicelo esilula nesincinci.
I-LT3514 isebenza ngamandla kwiimeko eziphosakeleyo. Umjikelo we-Cycle by-cycle incopho yangoku umda kunye nokubamba i-diode yangoku yokuva umda wokukhusela i-IC ngexesha leemeko zokugcwala. Ukuvalwa kweTher-mal kukhusela ukutshintshwa kwamandla kumaqondo obushushu aphezulu. I-Soft-start inceda ukulawula i-peak inductor yangoku ngexesha lokuqalisa.
I-LT3514 ikwabonisa ukulandelwa kombane ophumayo kunye nolandelelwano, ukuphindaphindeka okucwangcisiweyo, ukuvalwa kwe-programmable undervoltage, kunye nepini elungileyo yokubonisa xa zonke iziphumo zilawulwa.
I-LT3514 ineshaneli enye encinci (CH2) kune-LT3504, kwaye ineshaneli enye (CH3) ekhupha i-2A endaweni ye-1A. I-LT3514 kwi-QFN i-pin iyahambelana ne-LT3504. I-LT3504 ibonelela ngeziphumo ezine ze-1A
