TLV62065: About Vref

mayumi.T

Part Number: TLV62065
Other Parts Discussed in Thread: TPS62097, TLV62085, TLV62084A, TLV62569

Hi,

My customers need to set the output voltage of TLV 62065 to 1.1 V (≤ ± 3%).

They are referring to Equation 2 of the data sheet to calculate the output accuracy.
Vo = Vref + (1 + R1 / R2)

In the data sheet,
There are the maximum value and the minimum value of Vfb, but Vref is only the typical value.
Is the accuracy of Vref equal to the accuracy of Vfb?

Thank you.

Yes.

But the TLV62085 and TPS62097 offer tighter output voltage accuracy as well as higher efficiency and are recommended.

Dear Glaser-san

Thank you very much for your reply and suggestions.
I will tell the customer about the accuracy of Vref.

They prefer packages with thermal pads over HotRod's packages.
My customers will be pleased if there is a product with a thermal pad with the same specifications as TLV 62085.

Thank you for the feedback.

There is also the TLV62084A which gives better efficiency and faster transient response. Or the TLV62569 which is lower cost.

Dear Glaser-san

Thank you for the information.
I will ask the customer if they can use TLV62084A.
