Preliminary Information - Jan 21, 2015
E522.84/85/86/87
5.6 Typical Performance Figures
Figure 4. Fast Supply Step ( Startup )
Figure 5. Slow Supply Ramping
Typical Startup from unsupplied to 16V, Delay to deliver cur-
rent is <40µs.
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.
Dark-Blue: VS-Supply, Bright-Blue: LED voltage,
Purple: Current Probe for LED current
Figure 6. Very fast VS Stepresponse ( 8V to 25V )
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)
