SC1110
Not Recommended for New Designs
Not recommended for new designs.
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.
Features
- Generates termination voltages for active termination schemes
- 1% set point accuracy
- For ± 7 A output current, transient regulation is better than ± 80 mV
- VREFIN pin available for external 50% resistive divider to allow termination voltage track of the chipset voltage
- Buffered VREFOUT for system usage
- RDSON sensing for over-current protection in hiccup mode
- Soft start and logic input enabling
- 250 kHz switching for best transient and efficiency performance
- Gate drive capable for 0.5 A sourcing and sinking
- DDR memory systems
- Active termination schemes in high-speed logic systems
Applications
Packaging
- SOIC-14
- TSSOP-14
