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 i.
synchronous rectification, multiphase link capability, programmable secondary side delay, programmable switching frequency and programmable maximum duty cycle. It is designed for either current mode or voltage mode operation. The SC4910A has a typical turn-on threshold of 9V and the SC4910B has a threshold of 4.5V. SC4910A/B Features Synchronous rectification with adaptive control Programmable secondary side delay Programmable switching frequency Programmable max. duty cycle Remote voltage sense capability Close-loop soft start with active low shutdown 0.75V precision.
