NCP5203 2- in- 1 DDR Power Controller
The NCP5203 2- in- 1 DDR Power Controller is a plete power solution for an ACPI pliant high current DDR memory system. This IC bines 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,...
