Hi everyone,
I want to make an AC current source design for driving solenoids.
I want to change its frequency by a microcontroller. Vin should be around 3.3 volts, and Iout max should be 300mA. Output frequency range would swing around 50-200 hz.
Thanks for any advice in advance.

Hi Everyone!
For powering a microprocessor with a 3.7 volt liPoly battery, is the voltage regulator is neccessary? I know that would be better but 3.7 to 3.3v regulators are quite hard to find.
Also, what is your power setup for using liPoly as main source for micrcontroller projects?
Thanks.
