First stage of creating a power supply for my h-bridges. This will convert +12V to +21V and +5V. I use the LM3524D chip for controlling the PWM to the step-up circuit. I use a small mosfet to get the PWM signal inverted, and then a power mosfet to invert (and boost) the singnal again. This will run at 16kHz. And I believe it will be able to output 1A at +21V. For the +5V I use a common TS7805CI. This will do 1.5A at +5V. I'm adding a lot of connectors so I will be able to connect at least 4 double h-bridges for my 4 axis CNC project.
