current of 12 A and LDP-CWL 06-20 can achieve rise times less than 4.8 µs at an
output current of 6 A.
With the potentiometer 2 (adjust V
dc_link
, measurement point 2; refer to section
“How to get started”), the DC link voltage can be adjusted (refer to section “Laser
Driver Block Diagram”) to increase the collector emitter voltage of the transistor of
the linear regulator, to achieve higher bandwidths for waveforms such as pulsed or
rectangle waves.
DC link voltage has to be less than V
cc
-10 V and more than 5.5 V
+ V
compliance
to achieve higher bandwidths.
Frequency Response
The following graph demonstrates the 3dB bandwidth for increasing output current
values of the LDP-CWL 12-20 in manual modus. The following measurement
results are made on a dummy diode with a compliance voltage of 12 V.
