Special Purpose Regulators datasheet and documents for RT8207PGQW

RT8207PGQW

Special Purpose Regulators Overview

The RT8207PGQW is a complete power supply controller designed for DDRII, DDRIII, and low-power DDRIII/DDRIV memory systems. It integrates a synchronous PWM buck controller with a 3A sink/source tracking linear regulator (VTT) and a buffered low-noise reference (VTTREF). The device supports an adjustable output range from 0.75V to 3.3V and accepts battery input voltages between 2.5V and 26V. Key electrical parameters include 1% VOUT accuracy over line and load conditions, quick load-step response within 100ns, and resistor-programmable switching frequency. It features over/under voltage protection, power-good indication, and high-Z support in S3 states.
