Abstract
A power supply having an specified hold-up time to take a input voltage and convert it to an output voltage, comprising: a first power stage to receive the input voltage; a second power stage to generate the output voltage and an output current; an intermediate charge storage device coupled between the first and second power conversion stages providing an intermediate output voltage in response to the input voltage; and a controller that controls the intermediate output voltage according to a voltage function that is associated with the hold-up time.
