TPS56C215: Inductor Value Limitations

Part Number: TPS56C215

I'm designing a buck circuit with an input voltage of 12V and an output voltage of 1V using the TPS56C215. The datasheet recommends using about a 1uH inductor for this application. However I already have a 2.2uH inductor in my system that I use in high volume with a great price.

Are there any issues with stability if i use a 2.2uH inductor for this application?

hi, I am looking into this question, and give you feedback 4/8 after China Qingming festival.

Hi,Mark

The inductor design is also relative with frequency/output capacitance, could you share us the frequency setting and total Cout parameters?

Hi Mark,

I'd like to close it as no further reponse from your side. Please contact my by email wuyang-zhang@ti.com if you have other concern. Thanks.
