Hello~
Please let me ask one question for the sluu355a (UCC28810EVM-002 User's Guide).
There are dimming control with external or on-board PWM in buck Side (UCC28811).
PWM signal for dimming is connected to VSENSE pin of UCC28811.
The User's Guide of UCC28810EVM-002 (page 3) say freq. Range is 200Hz to 1000Hz, but I couldn't understand exactly the relationship between PWM freq. range and VSENSE control scheme.
Would you please provide some help what I can understand control scheme of PWM dimming?
It will be very helpful to us to move forward our design.
Thanks...
