DESCRIPTION
The SC1110 is a low-cost, full featured, synchronous voltage-mode controller designed to generate termination voltage in double data rate (DDR) memory systems and other applications where wide data bus need to be actively terminated. Synchronous control of the MOSFET half bridge allows power flowing bidirectionally. The termination voltage can be tightly regulated to track the chipset voltage, i.e. to be exactly 50% of that at all times. The SC1110 is ideal for low cost implementation of termination voltage supplies.
