NCP5201  
Dual Output  
DDR Power Controller  
The NCP5201 Dual DDR Power Controller is specifically  
designed as a total power solution for a high current DDR memory  
system. This IC combines the efficiency of a PWM controller for the  
VDDQ supply with the simplicity of a linear regulator for the VTT  
memory termination voltage. The secondary regulator (VTT) is  
designed to automatically track at half the primary regulator voltage  
(VDDQ). An internal power good voltage monitor tracks both  
VDDQ and VTT outputs and notifies the user in the event of a fault  
on either output. Protective features include soft−start circuitry and  
undervoltage monitoring of VCC and VSTBY. The IC is packaged in  
a 5 × 6 QFN−18.
