Hi Sir,
We need a boost mode LED driver, please find the specification on below.
1. Vin is a 3v Lithium Battery.
2. Vf of LED is 3.5V.
3. ILED is 30mA.
I saw there is a 2-8 LEDs application on the datasheet. May I know TPS61158 could support 1 LED application or is there any other better solution? Thanks.
