RT8204LGQW

Overview

The RT8204LGQW is a single synchronous buck PWM controller manufactured by Richtek Technology Corporation, housed in a 16-pin WQFN EP package. It provides high efficiency, excellent transient response, and high DC output accuracy for stepping down high voltage batteries to generate low voltage CPU core, I/O, and chipset RAM supplies in notebook computers.

Feature Summary

• Integrates an LDO controller alongside the primary PWM buck controller
• Designed for high-efficiency power conversion with superior transient response capabilities
• Ensures high DC output accuracy suitable for sensitive processor power rails

Applications

• Notebook computer CPU core power generation
• Notebook computer I/O power supply
• Chipset RAM power supply

Procurement Notes

Verify the specific suffix 'LGQW' against the manufacturer's current datasheet to confirm pinout and feature set compatibility. Ensure the component source is authorized to avoid counterfeit parts. Check for any recent product change notices or end-of-life announcements from Richtek Technology Corporation before finalizing procurement plans.

Selection Notes

Select this component when designing main power supplies for battery-powered notebook systems requiring a single synchronous buck topology. It is appropriate for applications needing integrated LDO functionality for auxiliary rails. Consider thermal performance and input voltage range compatibility with the system's battery configuration during selection.

Part Context

This part belongs to the RT8205 family of high-efficiency main power supply controllers for notebook computers. While similar to the dual-output RT8205 variants, the RT8204LGQW specifically features a single synchronous buck controller architecture combined with an LDO, tailored for simpler multi-rail requirements in portable computing devices.
