♠ 40VIN, 75VOUT LED Controllers
Iyo LT®3755, LT3755-1 uye LT3755-2 ndeye DC/DC ma controller akagadzirirwa kushanda seanogara-azvino sosi yekutyaira yakakwira ma LEDs. Ivo vanotyaira yakaderera divi rekunze N-chiteshi simba MOSFET kubva mukati yakadzorwa 7.15V inopa. Iyo yakagadziriswa frequency, ikozvino modhi yekuvakisa inoguma mukushanda kwakagadzikana pamusoro pehupamhi hwekugovera uye kubuda voltages. Iyo ivhu inotaridzirwa voltage FB pini inoshanda seyekuisa kune akati wandei ma LED ekudzivirira maficha,uye zvakare inoita kuti zvikwanise kuti chinoshandura chishande sechinogara-voltage sosi. Pini inogadzirisa inobvumira mushandisi kuronga frequency kubva pa100kHz kusvika 1MHz kuti agone kunyatsoita, kuita kana saizi yekunze kwechikamu.
Iyo LT3755/LT3755-1/LT3755-2 pfungwa inobuda ikozvino padivi repamusoro retambo ye LED. Yakakwirira divi yazvino kunzwa ndiyo inonyanya kuchinjika chirongwa chekutyaira maLED, achibvumira kuwedzera, buck modhi kana buck-boost modhi yekumisikidza. Iyo PWM yekupinda inopa ma LED dimming ratios anosvika 3000: 1, uye iyo CTRL yekuisa inopa imwe analog dimming kugona.
