The RT8248A provides a complete power supply for DDR2/
DDR3/DDR3L/LPDDR3/DDR4 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 low quiescent current,
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. RT8248AGQW资料下载
