Compensation Design for Peak Current-Mode Buck Converters

WebJun 8, 2024 · During the converter on-time, the switch or inductor current rises to Iout + ILp-p/2. During the off-time, the current decreases to Iout – Ilp-p/2 and the output current is the average current. For peak current limit, the switch current is compared to the current limit value during the on-time. WebA dominant pole represents the current-source effect, and a double pole at half the switching frequency shows the subharmonic oscillation. Current-mode control can become unstable even at duty cycles below 50%, and a compensating ramp must be added for some converters that are limited to 50% duty cycle.
