NCP5220A
3−in−1 PWM Dual Buck and Linear Power Controller
The NCP5220A 3−in−1 PWM 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 controllers 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 half of the reference voltage with sourcing and sinking current.
Protective features include, soft−start circuitry, undervol...
