Inquiry for boost IC [Copy link]

I have asked about the power supply at 15 meters underwater before. The current external power supply is 12V from the solar panel when the sun is there, and 11~13.2V and 20A from the battery when the sun goes down. Currently, Senser can accept a wide voltage input of 12~24V, but if the battery voltage is 11V, the sensor will not work, so I want to increase the voltage to 15V.
1. I would like to ask if there is any recommendation for a power IC that can input 11V~13.2V and then increase the voltage to 15~24V, and the current only needs to be around 200mA.
2. Because of this case...only one set will be produced. So I hope the power IC can be bought directly online as much as possible, thank you.

If you only need one set, you might as well buy a ready-made boost module, 15V 200mA is not a big power.

What the above said makes sense

The boost chip is not difficult to find.

I can only make one set, and I estimate that I need to experiment with 3 sets when doing experiments. After all, it takes at least 5 sets to make PCB boards and buy samples.

You can find the boost chip on TI or ADI official website.

MC34063 boost is also OK, now is an emergency period, it is easy to buy

If you only need one set, it is more appropriate to buy a ready-made boost module.

I understand, because it seems to be a similar tender. I only need one set that is sold out. Then I will directly look for a ready-made boost module on the market.

Understood, I'm looking for finished products on the market

OK, I'll check out MC34063 too, thanks

I have used TI's buck-boost IC. If you don't have any requirements for cost, you can go to TI's official website to check it out.
