♠ I-60V ePhakamileyo yangoku ye-Down-Down isiLawuli somqhubi we-LED
I-LT®3763 yi-frequency esisigxina, i-synchronous, i-step-down DC / DC isilawuli esenzelwe ukulawula ngokuchanekileyo imisinga yokuphuma ukuya kwi-20A. Umlawuli wemowudi yangoku uya kugcina ulawulo lwangoku lwe-inductor phezu koluhlu olubanzi lwe-voltage ukusuka kwi-0V ukuya kwi-55V. Isiphumo sangoku sisetwa yi-analog voltages kwi-CTRL pins kunye ne-external sense resistor. Ukulawulwa kwe-voltage kunye nokukhuselwa kwe-overvoltage kusetwa kunye ne-voltage divider ukusuka kwimveliso ukuya kwi-pin ye-FB. I-frequency switching is programmable ukusuka kwi-200kHz ukuya kwi-1MHz ngokusebenzisa isichasi sangaphandle kwi-RT pin okanye nge-SYNC pin kunye nesignali yewotshi yangaphandle. Uluvo lwangoku lokungena kunye nemveliso lubonelela ngokucutha igalelo langoku kunye nomlinganiselo ochanekileyo wale misinga. I-pin ye-FBIN ibonelelwe kwizicelo ezifuna umsebenzi wokulandelela amandla aphezulu.
Iimpawu ezongezelelweyo ziquka i-voltage echanekileyo yereferensi yangaphandle yokusetyenziswa kunye nezikhonkwane ze-CTRL, i-UVLO / i-EN pin echanekileyo evumela i-UVLO hysteresis ecwangcisiweyo, umqhubi we-PWM wezicelo ze-LED, ukufumanisa impazamo yombane ophumayo, kunye nokuvalwa kwe-thermal.
