RT8231B, RT8231A Datasheet - RICHTEK

RT8231B Complete DDR Memory Power Supply Controller

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 PWM controller provides the low quiescent current, high effici.

RT8231B Features

* PWM Controller  Adjustable Current Limit with Low-Side RDS(ON) Sensing  Low Quiescent Supply Current  Quick Load-Step Response within 100ns  1% VVDDQ Accuracy Over Line and Load  Adjustable 0.675V to 3.3V Output Range for 1.8V (DDR2), 1.5V (DDR3), 1.35V (DDR3L), 1.2V (LPDDR3), 1.2V (DDR4)
