Description
RT8231AGQW Richtek Memory Power Supply Controller, Current-mode, 480kHz Switching Freq-Max WQFN-20
The RT8231A/B provides a complete power supply for DDR2/DDR3/DDR3L/LPDDR3/DDR4/LPDDR4 memory systems. It integrates a synchronous PWM Buck controller with a 1.5A sink/source tracking linear regulator and buffered low noise reference.
The RT8231A/B 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 RT8231A/B provides protections including OVP, UVP, and thermal shutdown. The RT8231A/B is available in the WQFN-20L 3×3 package.
