There are several ways to implement the current/voltage control for an SMPS. The easy way I see is to use an ASIC/PMIC to manage the control loop. One of the other methods would be implement a PID control algorithm using a microcontroller and control the duty cycle of an SMPS.
I need some help in understanding the pros and cons of the above two methods in order to arrive at a justification of selecting one of the two methods.
Besides, if in case, there are control/communication/dimming requirements, then a PMIC with an MCU could also be used.
Please support me with some comparison.
