Hi ,
I am connecting TPS61194-Q1 PWM pin to a MCU , in that at when PWM pin is pulled ground ( continuous zero ) the screen turn blank , Can I or the PWM signal with Vref ~1.2V & then give to PWM pin so when the PWM from the MCU is pulled zero , VREF appears at PWM pin . Is this acceptable , because as per internal block diagram of IC it needs PWM to control brightness .
Please guide me. I basically need a min brightness , the screen should not turn blank.
