LD8928CA11Synchronous Rectification Driver
LD8928CA11 is a secondary side synchronous rectification (SR) IC with drive element and MOSFET. It is suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode.
LD8928CA11 can generate its own supply voltage through low output voltage or high side rectification applications to charge battery.
To reduce assembly process, layout area, and production cost, SR MOSFET and LD8928CA11 control core are packaged in SOP-8.
Features
- Suited for low side and high side flyback synchronous rectification in CCM, DCM and QR(valley lock) mode
- Suited for forward freewheeling rectification in CCM and DCM
- Self-supplying for operation with low output voltage and/or high–side rectification without an auxiliary winding
- Suited for primary side with peak load function (max. frequency 130kHz)
- VCC range from 3.4V to 14V
- Fast turn-off total delay of 30ns
Applications
- Switching AC/DC adaptor and battery charger
- Open frame switching power supply
