Power management solutions company, ON Semiconductor, expanded its power-computing portfolio with the introduction of the NCP5214. This new DDR memory power controller integrates VDDQ and VTT termination voltages.
This integration simplifies overall motherboard design and saves space in portable-computer applications, claims ON. The VDDQ voltage is supplied by a high-efficiency, synchronous, PWM controller that drives two external N-channel MOSFETs. The VTT termination voltage is supplied by a linear regulator that is set to track one half of the VDDQ voltage. The VTT regulator is specified at a robust source/sink capability of 2.4 amps peak.
