Fast transient response DC–DC converter with start-up in-rush current control

A new alternative to achieve fast transient response while inherently managing the in-rush current during DC/DC switching converter start-up is proposed. An AC coupled feedback (ACCF) is introduced using a capacitor multiplier from the output of the converter to the output of the error amplifier. With this additional feedback, the transient response, which used to be limited by the compensator mid...
