NCP5218 2 in 1 Notebook DDR Power Controller The NCP5218 2 in 1 Notebook DDR Power Controller is specifically designed as a total power solution for notebook DDR memory system.

This IC combines the efficiency of a PWM controller for the VDDQ supply with the simplicity of linear regulators for the VTT termination voltage and the buffered low noise reference.

This IC contains a synchronous PWM buck controller for driving two external NFETs to form the DDR memory sup
