Other Parts Discussed in Thread: TPS61158

Hi Team,

Is there efficiency data for 3 LEDs in series?
I found efficiency data of 6 LEDs in series.

My customer wants efficiency data under the following condition.
------------------------------------------
Vin: 3.6V
L: 10uH
LED current: 0～20mA
Vf of LED: 3.2V (20mA)
LED(#): 3 LEDs in series
------------------------------------------
Your support would be appreciated.

Hi,

I don't have that data readily available. It will take a few days to collect.

Hi Angelos-san,

Could you please collect the efficiency data?
My cutomer considers TPS61158 but there is a competitor, so it is helpful to show the data.

Best Regards,
