Internally-compensated ACM is a ripple-based, peak-current-mode control scheme that uses an internally generated ramp to represent the inductor current. This control mode provides a balance between the fast transient response of non-linear control modes (D-CAP™, constant on-time, and so forth) and the broad capacitor stability of other externally-compensated, fixed-frequency control modes (voltage mode, current mode). Internally-compensated advanced current mode provides a fixed, predictable frequency and a simplified compensation selection to reduce external components.
When to use: When fixed frequency and/or stack ability is needed with good output capacitor tolerance and a simplified compensation selection.
