描述 Description
The SRK1001 controller is designed for secondary side synchronous rectification
(SR) in flyback converters, suitable for operation in QR and mixed CCM/DCM fixed
frequency circuits.
It provides a high-current gate-drive output capable of driving N-channel Power
MOSFETs.
The control scheme of this IC is such that the SR MOSFET is switched on as soon as
current starts flowing through its body diode, and then switched off as current
approaches zero.
The fast turn-on with minimum delay and innovative adaptive turn-off logic allow
maximizing the conduction time of the SR MOSFET and eliminating the effect of
parasitic inductance in the circuit.
The device enters low consumption mode when it detects primary controller burstmode
operation, or when the DIS pin is pulled up by the user, or when the SR
MOSFET conduction falls below the programmed minimum TON. This improves the
converter efficiency at light load, where synchronous rectification is no longer
beneficial.
After the converter restarts switching or the DIS pin goes low again and the IC
detects that the current conduction in the rectifiers has increased 20 above the min
TON programmed value, the IC exits low consumption mode and resumes switching
operation.
