7 Control Loops
This section summarizes the basics in SMPS control with the XMC series feature set.
XMC4000 series with focus on High-end systems.
XMC1000 series with focus on Mid/Low-end solutions.
Beside the essential Sense and PWM Drive capability, there are advanced modulation add-on
qualities.
7.1 Using CSG (HRPWM) with an Internal Comparator and Slope Generator
This scheme can represent current mode control loops by using a High-end XMC device. This
example uses PCC.
The most prominent features for the modulation functionality (beside interconnectivity) are add-ons
such as CSG and HRPWM (High-Resolution-PWM) (Note that HRPWM is not illustrated in this
example)
