SRK1004 Synchronous Rectifier Controllers

STMicroelectronics SRK1004 Synchronous Rectifier Controllers are intended for secondary side synchronous rectification (SR) in Non-Complementary Actively Clamped Flyback, Resonant Flyback, and QuasiResonant Flyback converters. It provides a gate-drive output suitable for N-channel logic-level or standard-level power MOSFETs. The control scheme of this device is such that the SR MOSFET is switched on as soon as current starts flowing through its body diode and then switched off as the current approaches zero. When operated in a low-side configuration, the device can be supplied directly from the converter’s output voltage. Powering the STMicroelectronics SRK1004 from a dedicated auxiliary winding is recommended when used in the high-side configuration. When operated in a high-side configuration, a special function enables quick detection of short-circuit conditions to inhibit its operation as if the IC were powered directly from the output voltage.
