Hi all,

I need a current controlled pwm driver for PMOS. The Vds is 60V, Imax =>50mA,and Vref is 5V Vout= 6V, L = 1.02mH Cout= 5uH. Rload =100ohm.

Previously, I was planning to use voltage controlled pwm driver, but it is not widely used as much as Current controlled is used. I will use this pwm driver after the compensation network in the LTspice or cadence simulation.
Thanks for your help!

please see the attached file.
I have another question regarding to the error amplifier compensation.
I found that circuit from the web and I have no clue how did they calculate the compensation components. Can you also please help me how can i find this compensation values?
