indulis said:ESR is important... the ripple current thru the cap ESR is heat. The lower the ESR the lower the temp rise of the cap.
To address your original question about the ripple current equations... the Maxim part is not a fixed frequency device. The frequency moves around depending on the load and duty cycle.
Have you look at any of the PWM's from Linear?
