... If the inductor value is low or the load current is light, then the inductor current may become discontinuous. This occurs when I of discontinuous mode operation, see Linear Technology Application Note AN44. Also, high duty cycle operation may require slightly higher inductor values to avoid sub- harmonic oscillations ...
