this chip when one uses the appnote, delivers Heavy but short current spikes to the load.
When running at 12Vin that is not an issue since the pulses only come at abt 40kHz.
But when running it at 6.5V, which one appnote says should be possible, then the current
spikes arrive at a frequency of abt 500kHz.
This means that the heating of the LEDs becomes significantly higher and is a hazard.
My question is this:
- is it possible to Place an cap of 22uF 25V X5R after the sense resistor and to GND without¨getting any
problem with the constant current Control? This function uses the voltage over the sense resistor
to Control the current.
This is urgent, thanks!
