TL5001A-Q1: can take 12v@ 22 A output from 8 to 40 v input using tl5001a-q1?

Hi,

We required 12 v 22 A output from the 8 to 40 v input. Can i select the tl5001a-q1 IC for this application?

If this IC is not suitable, Please suggest any other best buck boost regulator supporting up to 22 A output. with high efficiency.

    Hi vignesh,

    With your maximum input voltage of 40V, you are hitting the maximum operating voltage of the TL5001A. The LM5155 (http://www.ti.com/product/LM5155-Q1) can be used in a buck-boost regulator configuration that will support 12V, 22A output. This can be done via a flyback or SEPIC configuration depending if isolation is required or not.

    If isolation is not required, and a four-switch buck boost topology is desired, I would recommend using the LM5176 (http://www.ti.com/product/LM5176) but this configuration only has FPWM and no diode emulation mode. However, this can be circumvented by using reverse current protection if needed. 

    Nevertheless, I think that these two ICs can give you a better performance than the TL5001A. 

    I hope this helps you make a decision.

    Thanks,

    Richard
