TPS6240x Series Step-down converter's internal resistor network values for fixed voltage versions.

You should use the adjustable TPS62400 for this.

OF course it is possible to use the ajdustable part, but if I use one of the fixed voltage regulators (TPS62402 or TPS62404), I will save 3 resistors and precious space on my design :)  I need one 3V3 and a 2V8 rails.

What are the internal resistor values for TPS62402 and TPS62404, which set the output voltages?

Many thanks,
James.

I think the D/S is pretty clear that FB1 needs to be connected directly to the output voltage, so it is not recommended to do what you are doing.

If you need smaller size, there are many new devices that offer this--TPS626xx, TPS826xx, TPS6223x, etc.

Thanks Chris for the suggestion.  I will use 2 TPS6223x devices instead.

However, regardless of datasheet recommendations, do you know the values of the internal resistors anyway?
