NCP5214EVB 数据手册
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.
