Hi Sir,

My customer would like design LED driver G5126.

Would you please provide recommendation for this?

hi SHH

I guess you would like to get an alternative device for this, so I think TPS92360 can be the option.

Hi Mason,

thanks for feedback. would you please provide comparison table for these two devices?

hi SHH

I just notice that G5126 uses PWM dimming, is this a must requirement?

TPS92360 uses analog dimming.

Hi Mason,

PWM input is required. any solution we can promote?

hi SHH

for TPS92360, it also uses PWM input. The difference between analog dimming(TPS92360) and PWM dimming(G5126) is that analog dimming controls amplitude of LED current to control brightness while PWM dimming repeatedly turns on and turns off LED current and control brightness by changing average LED current. So here I would like to confirm if this is a must. otherwise we have multi-channel device for PWM dimming, TPS61196.
