Compensator without Amplifier and Compensator with Amplifier are the compensator simulation results with and without the primary internal amplifier based on the PMP40274 board parameters. For the compensator without amplifier, the Rpullup resistor is 4kΩ pulled up to BP. The intersection between the Rpullup resistor and BP connects to comp and FB connects to ground. There is no difference for compensator bode plot when meeting Equation 3.
