♠ TPS92638-Q1 8-Channel Linear LED Driver Ine PWM Dimming
Iyo TPS92638-Q1 ndeye sere-chiteshi mutsara we LED mutyairi ane PWM dimming control.Dhizaini yayo yakanakira kutyaira akawanda tambo dze LEDs kusvika pakati
simba range.
Chishandiso ichi chinogona kutyaira tambo dzinosvika sere ne LED imwe kusvika kumatatu mutambo yega yega, panguva yakazara kusvika 70 mA pachiteshi.Zvinobuda zvinogona kuenderana kupa yepamusoro-yazvino drive inosvika 560 mA.
Mune akawanda-tambo maapplication, chishandiso chinopa mukana wekuve neyakajairwa-cathode yekubatanidza ye LED stings.Saka, pane chete waya imwe chete yekudzoka inodiwa pachinzvimbo cheimwe pa LED tambo iyo system ine yakaderera-side ikozvino pfungwa yaizoda.
Chishandiso chine simba rekuchinja LED ikozvino pakati pepamusoro ikozvino uye yakaderera ikozvino yekumira uye muswe zvikumbiro.Maviri mareferensi resistors anoisa iwo maviri ma LED mazinga azvino kubva kune imwe neimwe inobuda.
Iyo inosanganisirwa tembiricha yekutarisa inoderedza iyo LED drive ikozvino kana iyo IC junction tembiricha yakadarika chikumbaridzo chekushisa.Iyo tembiricha pachikumbaridzo inorongwa kuburikidza nekunze resistor.Mumwe anogona kudzima iyo inopisa ikozvino-yekutarisa chimiro nekubatanidza iyo TEMP pini pasi.Kubuda kwejoni tembiricha seanoroji voltage inowanikwa senge fekitori chirongwa sarudzo.
