Greetings,
I just received the LT3598 demo board from Linear Technology and I have a few questions. Below you'll find the LT3598 datasheet and also the Demo circuit quick start guide.

In the Quick Start Guide, they say to connect the PWM pin to VIN. I'm wondering how I can adjust the PWM? In the schematic if I put another resistor from the CTRL pin to ground it would form a voltage divider. Thus, varying voltage. Or, would I put a resistor from the PWM pin to ground? Would this adjust the PWM? Also, what are the OPENLED, and SYNC pins for?
Thanks!
