High Performance Secondary Side Controller with Synchronous Rectifier POWER MANAGEMENT Description The SC4910A/B is an integrated, full featured, secondary side controller designed for use in single ended and isolated switch mode power supplies with synchronous rectification where efficiency and fast transient response are of primary concern.
The SC4910A/B has outputs for both primary FET and secondary synchronous rectification.
The primary drive output is designed to drive a small and low cost pulse transformer to isolate the primary FET driver.
The secondary control makes it much easier com to monitor and control the system load with tight control loops and implement load c...
