Hi all, I am wondering how I would connect this booster converter to an Arduino Uno. I want to power an op amp as 12V, but first I need to boost it to 15V. I want to power the op amp through my 5V pin Arduino pin. I eventually want to put this all on a chip.

The Arduino is not a power supply, and you are allowed only very limited current draw from the 5V pin (a couple of LEDs or sensors is OK). Power the DC-DC converter from the same source as the Arduino.

You can switch that DC to DC converter on and off via an Arduino pin by using a mosfet. It will present a load of around 200mA. If you want a 12 volt output, there is a 12 volt version available. I guess you mean you will put all the components on a printed circuit board (not a chip)

Sounds interesting. Can you post a block diagram of what you are trying to do. You want to put this in a chip Putting what you are asking on a chip will cost a lot. If you can find somebody to do it, a foundry to make it and realize you will need to purchase a bunch of the chips as well. Search for …

Please explain more.
