General Description
The SC480 is a combination switching regulator and linear source/sink regulator intended for DDR1/2/3 memory systems.
The purpose of the switching regulator is to generate the supply voltage, VDDQ, for the memory system.
Key Features
- include cycle-by-cycle current limiting, digital soft-start, over-voltage and undervoltage protection and a power good flag. For the VTT regulator, the output voltage tracks REF, which is ½ VDDQ to provide an accurate termination voltage. The VTT output is generated from a 1.2V to VDDQ input by a linear source/sink regulator which is designed for high DC accuracy, fast transient response, and low external component count. All three outputs (VDDQ, VTT and REF) are actively discharged when VDDQ is.
