Other Parts Discussed in Thread: TPS63802,
I'm trying to build a project where the source voltage is a standard 18650 battery. But the circuit requires 2 voltages - 3.3 and 1.3.
3.3V is for digital (MSP430) and analog (audio). 1.3V is for digital only (codec).
I found TPS61098 and it looks good for Vmin and Vmax, and it seems to be good in terms of output current (total should be < 20mA).
I read about "Working with Boost Converters", so I guess I could come up with a solution in a simpler scenario. But I don't know how to make 3.3 and 1.3 voltage outputs.
Should I use 2x TPS61098? Or should I use voltage divider to get that 1.3V (which is very inefficient)? please help with the solution.
Thank you!
