LM22674: Vout Range

Russell Wetherley1

Part Number: LM22674

Hello E2E,

I have a customer who is looking to do the following:

19.2 – 28.8V down to 16V with an output current of around 200mA.

Can they use the LM22674 in this configuration? I am not seeing the max Vout specified in the datasheet, but the see on the selector guideline that it can go up to 37V. But on Webench it is listed as a 5V max for Vout. Can you advise on what the output limit is?

Thanks!

Hi Russell,

The LM22674 maximum output voltage is 37V. When I try to simulate the 16V output from the product folder, I also see an error limiting the output voltage to 5V. When I simulate from the Webench home page, I am able to choose the LM22674 with an output voltage of 16V.

I will communicate this discrepancy to the Webench team, and I will ask them to fix this.

Best Regards,
Katelyn
