NCP5210  
3−in−1 PWM Dual Buck  
and Linear DDR Power  
Controller  
The NCP5210, 3−in−1 PWM Dual Buck and Linear DDR Power  
Controller, is a complete power solution for MCH and DDR memory.  
This IC combines the efficiency of PWM controllers for the VDDQ  
supply and the MCH core supply voltage with the simplicity of linear  
regulator for the VTT termination voltage.  
This IC contains two synchronous PWM buck controller for driving  
four external N−Ch FETs to form the DDR memory supply voltage  
(VDDQ) and the MCH regulator. The DDR memory termination  
regulator (VTT) is designed to track at the half of the reference voltage  
with sourcing and sinking current.
