1. A system, comprising:
a controller;
a power stage coupled to the controller; and
an inductor coupled to the power stage;
wherein the controller is configured to:
store a pending pulse width modulation (PWM) pulse;
determine an inductor current of the inductor is above a current limit threshold;
provide the pending PWM pulse a predetermined number of times; and
responsive to providing the pending PWM pulse the predetermined number of times, cease storage of the pending PWM pulse.
