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 +/- 2.0A 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, under-voltage monitoring of 5VDUAL, over current protection (OCP), and thermal shutdown. The IC is packaged in 18-lead QFN.
