Hi All,

I am trying to understand the operation of a ML4824 Boost circuit
operating in continuous mode using current mode control.

I wanted to draw the critical voltage and current waveforms at each
point through the circuit. Thus am trying to plot the ripple voltage
across a boost capacitor with respect to the input full wave rectified
100Hz voltage in steady state conditions.

How could I work out the frequency, phase and magnitude of this ripple
with respect to the input voltage to the circuit?

Could someone please point me in the correct direction?
Thanks,

I think you're looking for Fairchild AN42045, which is a re-issue of
Microlinear's AN-34. Formulas and scoped illustrations are provided on
pages 4 and 6.
