Bode plots for a hysteretic mode LED Driver?
Bode plots for a hysteretic mode LED Driver?
(OP)
Hello,
I have made a LED Driver with LM3404 Hysteretic LED Driver
LM3404 Datasheet:
http://www.national.com/ds/LM/LM3404.pdf
On page of the LM3404 datasheet under "Theory of operation" it says....
"Hysteretic operation eliminates the need for small signal control loop compensation"
A colleague has provided me with Bode Plots showing the gain and phase margin of this LED Driver.

Are Bode Plots plausible for a hysteretic mode LED Driver?
