3.3 AECM

AECM(Advanced Emulated Current Mode) control is based topology that combines the advantages of peak current mode control and D-CAP2 control, providing fast transient response with true fixed switching frequency. Its control loop is using an emulated current to improve its transient response performance. AECM can support both PSM and FCCM under light load condition.
