Bug Boost Regulator Circuit
This boost regulator is for those times when you have a 28v relay, but want to use it with a 12v source. The circuit is built around the National Semiconductor LM2585, and uses the energy stored in an inductor to boost the 12 to 28v. Output voltage can be varied by adjusting the ratio of resistor values on the feedback pin.
The voltage boost regulator circuit does it's switching around 100 KHz, but generates no noise if SMT components are used. Output is good for
