RT8207
Complete DDRII/DDRIII Memory Power Supply Controller
General Description
The RT8207 provides a complete power supply for both DDRII/DDRIII memory systems.
It integrates a synchronous PWM buck controller with a 3A sink/source tracking linear regulator and a buffered low noise reference.
The PWM controller provides the high efficiency, excellent transient response, and high DC output accuracy needed for stepping down high-
voltage batteries to generate low
voltage chipset RAM supplies in notebook computers.
The constant-on-time PWM control scheme handles wide input/output
voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively c...
