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

overcurrent protection, VDDQ overvoltage and undervoltage
protections, and thermal shutdown. The IC is packaged in DFN?22.
