We are attempting to find a TI solution to power our inverted supply on two LME49724, two OP1656, and two BUF634A.
The role of the LME49724 is an analog ADC input buffer, the OPA1656 and BUF634A are a DAC line out stage / and headphone amp.
We simply can't get the ADP5074 to work and regret not taking the time to find a TI solution; as these are the only things that ever seem to work for us.
Our power supply input is 12V switched supply and we're attempting to provide a +/-12V to our op amps. We're hoping to find a quiet solution for audio applications.
Hi, Aaron
Actually, we can configure Buck converter to buck-boost topology which can achieve -12V output.
You can refer below application note.
If need 3A Iout, you can select TPS54302.
And there is a new device TPS62933 you also can choose, it will RTM in December.
Between you suggesting this and now this product has completely disappeared. Any other ideas?

Hi Aaron,
Sorry that missing your point .
Considering this hot market, there is very hard to find some available inventory for almost all parts on TI.com and authorized distributors.
Better to place order as soon as possible and you can get the shipment earlier .
