LD8928A62Synchronous Rectification Driver
LD8928A62 is a secondary side synchronous rectification (SR) driver IC. It is suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode. For forward freewheeling rectification application, LD8928A62 can be applied in CCM and DCM operation.
LD8928A62 can generate its own supply voltage through low output voltage or high side rectification applications to charge battery.
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 PSR with peak load function (max. frequency 130kHz)
- Programmable turn-off level
- Fast turn-off total delay of 30ns
Applications
- Switching AC/DC adaptor and battery charger
- Open frame switching power supply
