TPS61193: LED driver survey

Part Number: TPS61193
Other Parts Discussed in Thread: LM3410

Hello,

I'm considering an LED driver with the following specs.
I think the TPS61193 will meet the requirements, but this product does not have a SEPIC evaluation board.
Do you have a product that meets the following specifications and has an evaluation board that allows you to consider the conditions?

(Specification)
VIN: 18V to 29V
VOUT (VLED): 16.4V to 25.6V
ILED: 80mA (only 1ch)
Dimming Ratio: 6000:1

Hi,

Please allow me some time to find the solution. May I know if digital interface like I2C is needed? And which dimming method would you prefer (anolog, PWM, hybrid)?

Thank you for your reply.
No I2C required. PWM is good for the DIM method.
It turned out that the TPS61193 SEPIC could not satisfy the specification.
Please let me know if there are any other products.

Best regards,

Hi,

You could consider our LM3410 which can be used as a SEPIC converter.
