1. A method for controlling a light-emitting diode (LED) driver circuit to improve transient performance, the method comprising:
using a comparator coupled to a current regulator to monitor a load current to detect an overshoot condition, the current regulator uses a first control voltage to generate an output voltage;
using a first compensation network to store the first control voltage;
in response to a user input, transitioning from the first compensation network to a second compensation network that stores a second control voltage;
operating a switch in a mode configured to limit the load current in a first array of LEDs; and
in response to detecting an absence of the overshoot condition, operating the switch in a regular mode.
