Abstract
The low-frequency, low power switching voltage switching pre-regulator is operable to propagate The pre-regulator is comprised of a chopping circuit, a pre-driver switching circuit and a feed back circuit. The output of the chopping circuit defines the output of the voltage pre-regulator and an input voltage is received at the input of the chopping circuit. The feedback circuit senses the magnitude of the voltage at the chopping circuit and derives a feedback signal in response thereto. The PWM interface circuit receives the feedback signals and a PWM signal of the type generally derived from a microprocessor. The PWM interface circuit switches the chopping circuit in response to the feedback and the PWM signals.
