NCP5220 3 in 1 PWM Dual Buck and Linear Power Controller The NCP5220 3 in 1 PWM a Dual Buck and Linear 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 memo
