The RT8207L/M provides a complete power supply for both
DDRII/DDRIII/Low-Power DDRIII/DDRIV memory systems.
It integrates a synchronous PWM buck controller with a
1.5A sink/source tracking linear regulator and 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 constant switching frequency.RT8207LGQW RT8207MGQW RT8207LZQW/RT8207LZQW(2) RT8207MZQW资料下载
