Switch Mode Power Supplies - Low Power Topology

Infineon Technologies SMPS - Low Power Topology is used for low power applications from 100W down to under 1W, where the output needs to be isolated from the input. Its offers cost effectiveness, simplicity, and ease of implementation. Discontinuous Conduction Mode (DCM) Topology is the popular operating mode for low current output and power levels below 50W. The low power Quasi-Resonant (QR) Topology is largely used in low power SMPS applications such as charger, adapter, and auxiliary supply.
