LM5088: LM5088 CC control

Hello Masazumi,

in order to implement current regulation (CC) you will need to measure the output current and adjust the output voltage to a set point. The baisc block diagram shows that you are adjusting Vout, but I cant see how you are measuring the output current? Regarding the Compensation, I would use the LM5088 Quickstart calculator at the max pout out, you should remain stable through the vout adjustment range as you regulate the current.

Please see below a simple CC CV regulator using the LM5117 below.

Hope this helps?
