LM3290: Alternative for LM3290-91-1EVM

Part Number: LM3290
Other Parts Discussed in Thread: LM3253

Hi Team,

A customer is previously using an LM3290-91-1EVM for their project and is looking for a replacement part.

I understand that the LM3290/91 devices has no direct replacements but I would like to know if there are other converters that can fill the purpose of the customer application below:

The envelope tracking board is used along with an RF power amplifier (adaptively tuning the supply voltage of the power amplifier depending on the input RF signal). I think any type of evaluation board that implements envelope tracking works for us. If the evaluation board includes both the envelope tracker as well as a power amplifier, it would be even better. For example, and RF PA with central frequency around 3.5 or 4.5 (sub 6 GHz) and a Bandwidth up to 100 MHz.

Thank you for the help.
