TPS61165: EasyScale: One-Wire Digital Dimming

Hi,

Can you provide more application requirement so we can check if there any new product better for your design 

Hi Andy,

I want to ensure that the output current will not include a ripple caused by dimming.

Analog dimming can achieve the requirement.  

Hi,

Can you use higher PWM freq like 20KHz---100KHz for dimming control? set the RC low pass filter corner freq below 1KHz for much lower ripple

Hi Andy,

What is the corner frequency value of the RC filter used in the TPS61165?

Can you confirm the FB fluctuation when using one-wire digital dimming?

Hi

What's Vin, Vout and LED current in your application? we may have new products with PWM dimming pin to simplify the design 

Hi Andy,

Vin=5V

Support 38V VOUT

Support 1.5A Switch FET

Hi,

Let me check and update you early next week,
