Getting Started
Adopting SW to Your LED Engine (5/6)
8. Open the UI of PDM_DIMMED_LED_LAMP APP
9. Change the Generated OFF-time based on the value measured
previously
– This is to ensure just enough time for the LED current to drop
to just below the reference level i.e. minimum ripple size
– In the example of LED engine A, this is 480ns
– Considering a propagation delay of 100ns, we shall set the
OFF-time to (480-100 = 380ns)
