NCP5214

2−in−1 Notebook DDR

Power Controller

The NCP5214 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

supply voltage (VDDQ). The DDR memory termination regulator

output voltage (VTT) and the buffered VREF are internally set to

track at the half of VDDQ. An internal power good voltage monitor

tracks VDDQ output and notifies the user whether the VDDQ output

is within target range. Protective features include soft−start

circuitries, undervoltage monitoring of supply voltage, VDDQ

overcurrent protection, VDDQ overvoltage and undervoltage

protections, and thermal shutdown. The IC is packaged in DFN−22.
