Hi,
I have a question about TPS61160 LED driver. Condition is below.
- 4 LED: Not white LED, typ.1.6V Vf / 1 LED
- CTRL: connect to 3.0V_REG
- LED current: about 2 - 40 mA (typ. about 15mA)
In the datasheet, "Maximum duty cycle" is shown about 93%.
Is it case by just using PWM input?
We will not use the PWM input for adjust a LED current. We think a constant voltage input operation with TPS61160, it looks good operation. Therefore duty cycle is 100% in this case.
Best regards,
KoT
