產品總覽

The RT8207GQW is a complete DDRII/DDRIII memory Power Supply Controller 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 constant switching frequency. It achieves high efficiency by eliminating the current-sense resistor found in traditional current-mode PWMs. Efficiency is further enhanced by its ability to drive very large synchronous rectifier MOSFETs. The buck conversion allows this device to directly step down high-voltage batteries for the highest possible efficiency.
  • Resistor programmable current limit by low-side RDS(ON) sense
  • Resistor programmable frequency
  • Over/under voltage protection
  • Drives large synchronous-rectifier FETs
  • Power-good indicator
  • LDO input available to optimize power losses
  • Supports high-Z in S3 and soft-OFF in S4/S5
  • 1% VOUT Accuracy over line and load
  • Quick load-step response within 100ns
