TPS61165: TPS61160 TPS61161 TPS61165 duty cycle accuracy when CTRL dimming mode

Part Number: TPS61165
Other Parts Discussed in Thread: LM36923, LM36274

Does TPS6116X has similar parameter of dimming width for RD design?

I see in datasheet, there is no min dimming duty cycle and min dimming time parameter. the blank is only one line

We demand to know the parts dimming duty cycly lower to 0.1% ~1%,  1%~5% accuracy to modify the backlight. It's more potential to influence the module and device compatibility, thanks.

    Hi Lanjie,
    Thanks for choosing TPS6116X, Those devices' output current tolerance depends on the FB accuracy and the current sensor resistor accuracy. The typical FB accuracy is 2%, so it's a little difficult to warrant it's accuracy under different application. If you need very high accuracy control , you can have try with like LM36923, LM36274, those device has very good accuracy with digital control. Thanks.
