Other Parts Discussed in Thread: TPS92692

Hi Team,

I have question about duty cycle and Analot-to-PWM dimming relative of TPS92692-Q1.
In my case, designed the DRL/PL current be 140mA/10mA.
1. May I know the 4% accuracy can effect the controller's duty work?
2. May I know the fPWN 250Hz suitable for controller?

Thanks!

Hello,

1. The TPS92692 is designed for 4% DC current acuracy and 5% from DIM/PWM to PDRV output for duty cycle control.
2. Fpwm of 250Hz is suitable for the controller.

Thanks Tuan
