Claim Text:
1. A method for providing slope compensation in a switched-mode power supply (SMPS) controller, said method comprising the steps of: turning on a pulse width modulation (PWM) control signal at a beginning of a PWM cycle; sampling an input voltage (v converting the sampled input voltage (v sampling an output voltage (v converting the sampled output voltage (v sampling an inductor current (I converting the sampled minimum inductor current value (I determining a digital slope compensated peak current reference (I converting the digital slope compensated peak current reference (I comparing the analog slope compensated peak current reference (I turning off the PWM control signal with an output from the analog comparator when the inductor current (I returning to the step of turning on the PWM control signal at the beginning of a next PWM cycle.
