Abstract

A synchronous-switch post regulator (SSPR) circuit based on a novel charge-pump gate drive is described. It resolves the technical barriers due to the difficulty of designing an effective gate drive and synchronized trailing-edge pulse width modulation (PWM) in a straightforward manner. It has been demonstrated that in the medium current range, the power loss of this SSPR is much less than when the linear regulator approach is used. With additional advantages of easy on/off control, better overcurrent protection, and the potential of being integrated into a monolithic IC, this SSPR compares favorably with the magnetic amplifier post regulators.<>
