Part Number: LM5155

Dear team,

At datasheet of LM5155, I can found system examples using LM5155 as a LIDAR bias supply(Figure 43,44).

Is there any reference design or design guide for Lidar Bias supply using LM5155?

Thank you.

Hi Dino,

Thanks for reaching out with your question and for considering the LM5155 in your application.

There are some high step up ratio designs for the LM5155 in a boost configuration. the designs can be found on the TI reference design website. What are your application specifications? VIN range, VOUT , IOUT, switching frequency requirements?

Feel free to contact me directly.

Thanks,

Garrett

Hi Garrett,

I can't find similar application on the TI reference design website.

- application : Lidar receiver bias supply.

- Vin : typ 24V , 20~29V

- Vout : max220V

- Iout : Hundreds of uA , below mA

- switching frequency : not fixed.

Thank you.
