NCP5203
2in1 DDR Power
Controller
The NCP5203 2in1 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
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 softstart, undervoltage
monitoring of 5VDUAL, over protection current (OCP), and thermal
shutdown. The IC is packaged in 18lead QFN.
