NCP5220
NCP5220 is PWM Dual Buck and Linear Power Controller manufactured by onsemi.
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 plete power solution for MCH and DDR memory. This IC bines 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 reference voltage with sourcing and sinking current.
Protective Features include, soft- start circuitry,...
