SMART LED DRIVER SOLUTION FOR DYNAMIC LED CHAIN

Circuitry configured to deliver an adjustable discharge current to a compensation node of a power converter that supplies a load, which may speed up the power to the load on the new steady state condition, while maintaining the stable response time of the power converter. A driver circuit may measur...

Beschreibung
Zusammenfassung:	Circuitry configured to deliver an adjustable discharge current to a compensation node of a power converter that supplies a load, which may speed up the power to the load on the new steady state condition, while maintaining the stable response time of the power converter. A driver circuit may measure current to the load and perform overshoot protection for the load. The overshoot protection may also generate a pattern of detectable square wave pulses. The circuitry of this disclosure may adjust the discharge current based on a duration of the pulses in the pattern of pulses, as well as based on a pulse density of the pulses.
