SRK1000 Switching Controller

STMicroelectronics SRK1000 Switching Controller is intended for secondary side Synchronous Rectification (SR) in flyback converters. This switching controller provides high-current gate drive output that is capable of driving N-channel Power MOSFETs. The SR MOSFET is switched on as soon as current starts flowing through the diode and it is then switched off as current approaches zero. This device enters low consumption mode when it detects primary controller burst-mode operation, or when the SR MOSFET conduction becomes lower than the programmed minimum T_ON. The STMicroelectronics SRK1000 Switching Controller is suitable for operation in QR and mixed CCM/DCM fixed frequency circuits. Applications include battery chargers, quick chargers, adapters, and USB power delivery.
