What is the relationship between peak inductor current and the load current of a buck converter working in discontinuous conduction mode?

27 May 2015 1 5K Report

Muhammad Aamir Abbas

I(inductor max)=Vo(1/R +(1-D)/2fL) where D is duty cycle, Vo is output voltage. Discontinous or continous mode depends on value of inductor which should be L>(1-D)R/2f for continous mode.

Whereas load current is Vo/R.
