NCP5203 2−in−1 DDR Power Controller
The NCP5203 2−in−1 DDR Power Controller is a complete power solution for an ACPI compliant high current DDR memory system.
This IC combines the efficiency of a PWM controller for the VDDQ supply with the simplicity of linear
regulator for the VTT termination voltage.
The NCP5203 contains a synchronous PWM buck controller for driving two external NFETs to form the DDR memory supply voltage (VDDQ).
The $2.
0 A user adjustable VTT terminator
regulator has short circuit protection.
An internal power good function monitors both the VDDQ and VTT outputs and signals if a fault occurs.
Protective features include soft−start, undervoltage monitoring of 5VDUAL, over ...
