ABSTRACT:
A DC-DC converter includes a blocking oscillator which is fed with a dc input from an input source and which oscillates to produce an output, which is rectified by a rectifier. The converter also includes an output voltage controlling transistor, the base of which is fed with the rectified output through a constant voltage element. The transistor controls a base current to an oscillating transistor which is contained in the blocking oscillator. The base current to this latter transistor is fed from the input source through a starting resistor and is also fed from the rectifier output through another resistor.
