Features
- The MK91808 is a compact secondary side synchronous rectifier controller and driver for high performance flyback converters. It is compatible with DCM, CCM and QR operations.
- Operates in a Wide Output Voltage Range Down to Zero Voltage.
- Self-supply for Operation with Low Output Voltage and/or High.
- side Rectification without an Auxiliary Winding
The MK91808 generates its own supply while used in high-side rectification, which eliminates the need of external supply ge.
