Ultra-Fast Turn-off Synchronous Rectifier Controller
Desciption
Features
The MK91808 is a pact secondary side synchronous rectifier controller and driver for high performance flyback converters. It is patible 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 generated by auxiliary winding of the transformer.
- Gate Drive Clamp Voltage is Up to 9V
- 10ns Fast Turn-off and 25ns Turn-on Delay
