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.
Feature Summary
- Integrates a synchronous PWM buck controller with a 3A sink/source tracking linear regulator and buffered low-noise reference
- Provides quick load-step response within 100ns and 1% VOUT accuracy over line and load conditions
- Supports high-Z state in S3 and soft-off in S4/S5 for enhanced power management
Applications
- DDRII/DDDIII Memory Power Supplies
- Notebook Computers
- SSTL18, SSTL15 and HSTL Bus Termination
Procurement Notes
Verify the specific suffix PGQW against official Richtek documentation to confirm package type and tape/reel specifications. Ensure compatibility with target DDR memory standards. Check humidity sensitivity levels and storage conditions prior to assembly. Confirm RoHS compliance status through manufacturer datasheets.
Selection Notes
Select this component for applications requiring integrated memory power solutions with precise voltage regulation. Consider the 3A LDO capability for VTT generation and the wide input voltage range for battery-powered devices. Evaluate thermal performance and PCB layout requirements for the WQFN package.
