NCP5203  
2−in−1 DDR Power  
Controller  
The NCP5203 2−in−1 DDR Power Controller is a complete power  
solution for an ACPI compliant high current DDR memory system.  
This IC combines the efficiency of a PWM controller for the VDDQ  
supply with the simplicity of linear regulator for the VTT  
termination voltage. The NCP5203 contains a synchronous PWM  
buck controller for driving two external NFETs to form the DDR  
memory supply voltage (VDDQ). The $2.0 A user adjustable VTT  
terminator regulator has short circuit protection. An internal power  
good function monitors both the VDDQ and VTT outputs and signals  
if a fault occurs. Protective features include soft−start, undervoltage  
monitoring of 5VDUAL, over protection current (OCP), and thermal  
shutdown. The IC is packaged in 18−lead QFN.
