5.6 Typical Performance Figures

Figure 4. Fast Supply Step ( Startup )

Figure 5. Slow Supply Ramping

Figure 6. Very fast VS Stepresponse ( 8V to 25V )

Typical Startup from unsupplied to 16V, Delay to deliver cur-

rent is <40µs.

Dark-Blue: VS-Supply, Bright-Blue: LED voltage,

Purple: Current Probe for LED current

Very steep rising and falling VS Supply,

8V to 25V at VS, Risetime approx. 14µs.

Purple Channel: LED Current

Bright-Blue Channel: LED Voltage

Dark-Blue Channel: VS Supply Voltage (Step)

Ramping of Supply in >20ms. Bright-blue channel shows the

LED driver output, dark-blue is the supply voltage at VS.

Purple Curve is the according current probed.
