Although the inclusion of the resistor will minimize or eliminate the load current spikes, the overall
current regulation and operating frequency will be slightly compromised. The resistor will reduce the
overall effectiveness of the output capacitor which means the switching frequency will marginally
increase. Likewise the output ripple current will also increase, which ultimately leads to a larger
current regulation tolerance. Although the overall current regulation capabilities may decrease with
the inclusion of this resistor, the actual stability of the PWM dimming signal will still be the dominant
factor of the overall output current regulation capabilities.
