资料介绍

By Jeff Falin Senior Applications Engineer A mathematical model is always helpful in determining the optimal compensation components for a particular design.

However, compensating the loop of a WLED current-

regulating boost converter is a bit different than compen-

sating the same converter configured to regulate voltage.

Measuring the control loop with traditional methods is cumbersome because of low impedance at the feedback

(FB) pin and the lack of a top-side FB resistor. In Reference 1, Ray Ridley has presented a simplified, small-signal control-loop model for a boost converter with current-mode control. The following explains how to modify Ridley's model so that it fits a WLED current-regulating boost converter; it also explains how to measure the boost converter's control loop.
