Hello

For small display, customer plan to use OLED type.

The OLED power rail are 5V(max 10mA), 12.5V(max 3mA) and 17V(max 20mA)
Supply power can be 9V~16V or just 3.3V either one.
Do we have any suitable solution combine 3 power rails or just use one controller and discrete components to design circuit? Thank you.

Patrick,

I think it would make more sense to have a buck-boost converter instead of a controller with external components, or something like a PMIC with all of these rails in it.

I have re-assigned this question to the low power buck-boost team as they should be able to help you better.

In the meantime it would be good to know how you plan on switching between these different OLED voltages. Are you going to use I2C commands, an adjustable reference voltage, enable pins, etc.?

Dear Nick

If have I2C, it would be better. If have suitable solution for it, please help advice. Thank you.

Patrick,

I haven't seen any updates on this. We have a section for LCD & OLED display power on TI.com. Hopefully you can find something that meets your requirements there.
