Simple DC DC Converter
This schematic shows you how to build a dc-dc schematic.Here's a DC to DC circuit put together just from parts found on the test-bench. All it took was two transistors, two resistors, an audio transformer, a bridge and two caps. It may not be the ultimate in performance, but it does work.
The key to how it works is the transformer. As you can see, two transistors drive the transformer primary with the base drive for each coming from the collector of the other.When power is applied, suppose Q1 turns on a few nanoseconds faster than Q2.
