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

with sourcing and sinking current.
Protective features include, soft?start circuitry, undervoltage
monitoring of 5VDUAL and BOOT voltage, and thermal shutdown.
