mc34063a tutorial
Hello, this is my first post here and I'm all together new with electronics, so I apologize in advance for my cluelessness.
I'm trying to design a PCB that will basically be an Arduino clone with on board H-bridges to drive some small DC motors, and Bluetooth to communicate with my Nokia N800 tablet. The PCB will control a small wheeled vehicle with a wireless video camera mounted on it.
I want to use a single LiPO battery as a power supply. Assuming I use a 3.7v cell, I'll need to regulate that to get what I need for my various components. I am thinking I would like to use an MC34063A boost IC to step up to 9v.
I don't really understand how to wire the MC34063A. **broken link removed** provides a pretty good calculator that takes the desired specifications (VCC in, VCC out, I out, Vripple, and Fmin) and output a schematic of the MC34063A with the other necessary components.
My camera needs 55mA at 9V, but I don't know anything about Vripple and Fmin. Can anyone enlighten me what these are and how I determine what their value should be in my circuit?
Thanks for the consideration,
CMD
