Hey Aaron, James,
Thanks a lot for your reply,

the customer says "since these products (LM3290 and LM3291) are still on the market, we can buy them in sufficient quantities, but we need datasheets. Can you send them to us? "

Best regards
Anil

Hi Anil,

I am still looking into this currently. Could you possibly send the application that this will be used for? In the mean time, I have some alternative parts that may work for you depending on the specifications that you need http://www.ti.com/lsds/ti/power-management/rf-dc-dc-converter-products.page.

Hey Aaron,
Thanks for your reply.
This is the customer's response

" We research 2W power amplifier for OFDM RF-modem (stream 5 or 10MB\s of SD or HD video). We need to decrease PAPR, so we are looking for hardware solution for envelope tracking power supply of amplifier. Could you recommend other solution instead of LM3290 and LM3291? "

Anil,

I talked to my team and since these are very niche devices with a small market, we are moving forward with obsoleting the LM3290 and LM3291 products. We currently do not have any replacements for them in our portfolio.
