Part Number: TPS61178
Other Parts Discussed in Thread: LM5112-Q1

Hello,

I need boost supply with input 12-14V(from car) to have output 17V/8Amax.

This will be used for supplying the LED.

Can you please help me with inductor selection, to give me proposal which to use for design?

(small footprint as possible, height is not problem).

Thanks in advance

regards

    Hi Stefan,

    The TPS61178 can't support 8A output current because of the current limitation and thermal. This device is not Q1 version device for automotive application.

    I would suggest boost controller LM5112-Q1. The external components selection can be found in Webench.
