Other Parts Discussed in Thread: TPS61099
I am searching for a boost converter to power the honey well SS495X-series of hall effect sensors:
That at minimum need an input voltage of 4.5V (7.0mA supply current at 5V supply voltage). I have thought about using a TPS61070 that should do the job.
II would be happy if you took a look at following questions:
- Can you recommend a boost converter that serve as a supply voltage for sensors? I guess the ripples should be quite low.
- My project should run on a lithium 3.0V coin cell, either the standard CR 2032 with a diameter of 20mm or the CR 1225 with a diameter of 12mm.
- I am also considering to use a LR 44 button cell with the same diameter as the CR1225 but 3x capacity. Then, I might need a boost converter for 3.3V and for 5.0V or: I just boost up to 5.0V and use 2xdiodes. What do you think about that?
Thank you and best!
