Abstract
A multi-mode converter using iterative average current mode pulse width modulation (PWM) control is provided. The converter may include a current sense amplifier configured to output a current sense signal over a present switching cycle based on an inductor current through an inductor, a voltage error amplifier configured to output an error voltage based on a difference between a reference voltage and an output voltage, and a PWM controller. The PWM controller may include an error voltage modifier circuit configured to selectively output the error voltage or a modified error voltage based on a mode signal, and an iterative average current control circuit configured to generate a PWM signal based on the output from the error voltage modifier circuit, the current sense signal over the present switching cycle and a current sense signal over a previous switching cycle that precedes the present switching cycle.
