Hi Vishwanath,

Buck devices cannot support 15Vin_min-24Vout (Vin lower than Vout), you may reach to buck-boost product line.

I will assign your thread to BCC product line.

Hi Vishwanath,

Thanks for reaching out.

You can look at LM5175 / LM5176 / LM5177 / LM51772 which are all Buck-boost controllers.

BRs,

Bryce

Hi Vishwanath,

a good starting point is the Webench:

WEBENCH-CIRCUIT-DESIGNER Design tool | TI.com

Here you can enter your design parameter and get some solutions suggested.

There are some more parameters which are important for selecting a DCDC solution beside the input and output voltage but for your setup you need a BuckBoost.

Best regards,

Stefan
