I study ADP8140 Rev. PrB datasheet about dimming control have many question. pls see below and provide your suggestion to me. thanks
Q1: The dataheet Page4. "DIM pin Frequency Range" highlihgt 140 Hz To 40K Hz. but with the PWM mode have any conversion formular?
Q2:The Figure 9. if my MCU using PWM mode to control ADP8140 DIM. How do I know then adp8140 output 100%,ADP8140 DIM pin frequency and PWM pulse is how much? Contrary when the ADP8140 output 0%,ADP8140 DIM pin frequency and PWM pulse is how much? another I want to ADP8140 output 0% to 100% is divided into 2n level so have any frequency/PWM conversion formular provide to me?
