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.
Features
- 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.
