To further enhance the efficiency performance, frequency reduction operation has been implemented into CoolSET™ Gen. 5 to achieve higher efficiency with lower switching frequency at mid and light load condition. In addition, for low AC line input operation, CCM (Continuous Current Mode) operation has been implemented to achieve lower conduction losses, thereby achieving a higher efficiency to meet international regulatory standards.

To further reduce BOM count and cost of a non-isolated flyback design, an integrated error amplifier is integrated to allow a direct feedback from the primary output with minimal components and complexity. The fifth Generation of CoolSET™ is available in both DIP-7 and DSO-12 packages.
