Power management solutions company, ON Semiconductor, expanded its power-computing portfolio with the introduction of the NCP5214. This new DDR memory power controller integrates V_DDQ and V_TT termination voltages.

This integration simplifies overall motherboard design and saves space in portable-computer applications, claims ON. The V_DDQ voltage is supplied by a high-efficiency, synchronous, PWM controller that drives two external N-channel MOSFETs. The V_TT termination voltage is supplied by a linear regulator that is set to track one half of the V_DDQ voltage. The V_TT regulator is specified at a robust source/sink capability of 2.4 amps peak.
