RT8207MZQW 製品詳細

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. The RT8207L/M achieves high efficiency at a reduced cost 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. The 1.5A sink/source LDO maintains fast transient response, only requiring 20μF of ceramic output capacitance. In addition, the LDO supply input is available externally to significantly reduce the total power losses. The RT8207L/M supports all of the sleep state controls placing VTT at high-Z in S3 and discharging VDDQ, VTT and VTTREF (soft-off) in S4/S5. The RT8207L/M has all of the protection features including thermal shutdown and is available in WQFN-24L 4x4 and WQFN-20L 3x3 packages.
