PARALLEL PLDS FOR HIGHER CURRENT
Multiple PLDxK-CH drivers can be connected in parallel to
drive higher current. Contact the factory for more information
on how to do this safely, or see Application Note AN-LD06:

POWER SUPPLIES AND NOISE
The PLDxK-CH drivers deliver stable current with low noise,
but the power supply you use will directly influence the noise
performance of the driver.
We recommend using a regulated linear supply for the
best noise performance, but depending on your application
requirements you may be able to use a switching power
supply. Each case must be evaluated because a switching
power supply will affect noise, transient, and stability
performance. Wavelength offers an evaluation kit and power
supplies for easy configuration and operation.
Wavelength offers two switching power supplies that may
work in your application.
