ABSTRACT:
In a transistor switching type voltage regulation circuit, energy precharge is provided in a by-pass loop around the switching transistor. The instantaneous peak power dissipation at turn-on through the switching transistor is thereby diminished, greatly increasing the reliability of the switching transistor.
