MK91806H
Ultra-Fast Turn-off Synchronous Rectifier Controller
Optimized for <1MHz Frequency
Supports DCM, QR and CCM Operations
Supports Active Clamp Flyback with GaN FET or Super-junction MOSFET at Primary Side
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
Gate Drive Voltage is Up to 9V
10ns Fast Turn-off and 25ns Turn-on Delay
VD/HVIN Pin Supports Negative Voltage Spikes Down to -3V
Avoids Potential False Turn-on during DCM
VG Clamping Circuit Works Well when VCC is Below 2V
Supports both High-side and Low-side Rectification
Adaptive Gate Drive for Maximum Efficiency
AC/DC Adapters for Mobile Phone and Notebook
High Power density AC/DC Power Supplies
