Abstract
A power converter includes a switching circuit, a power conversion circuit that receives an input voltage via the switching circuit and converts the input voltage into an output voltage, an input voltage sense circuit that detects the input voltage and generates an input voltage sense signal, and a PWM controller that adjusts a duty cycle of the switching circuit based at least in part on the input voltage sense signal. The power converter also includes an output sense circuit that detects the output voltage and generates an output voltage sense signal, wherein the PWM controller adjusts the duty cycle of the switching circuit based at least in part on the input voltage sense signal and the output voltage sense signal.
