Hi TI LED Driver Team,
I'm using TPS61165 for instrument cluster backlight driver and my schematic is as below:
And I'm using 5kHz to dimming the brightness, but when I decrease the PWM duty cycle to near 0.2%, it will enter into Easy-Scale mode sometimes. And the output current is wrong as below: Iout(green), PWM(yellow).
Do you have any commons on this phenomenon? How to avoid this kind of phenomenon? Thanks.
