RT8204AGQW

Overview

The RT8204AGQW is a single synchronous buck PWM controller manufactured by Richtek Technology Corporation. It features an input voltage range of 3 V to 26 V and utilizes a Buck-Synchronous topology. The device is housed in a 16-Pin WQFN EP package. Designed for high efficiency, excellent transient response, and high DC output accuracy, it steps down high-voltage batteries to generate low-voltage CPU core, I/O, and chipset RAM supplies in notebook computers.

Feature Summary

• Provides high efficiency and excellent transient response for power conversion applications
• Delivers high DC output accuracy suitable for sensitive processor loads
• Integrates LDO controller functionality alongside the primary PWM control

Applications

• Generating low voltage CPU core supplies in notebook computers
• Powering I/O circuits in portable computing devices
• Supplying chipset RAM in notebook systems

Procurement Notes

Verify the specific suffix 'GQW' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad specifications. Ensure the component matches the required 16-Pin WQFN EP package dimensions. Confirm that the application design supports the specified 3 V to 26 V input range before procurement.

Selection Notes

Select this controller when designing single-phase synchronous buck converters for notebook platforms requiring precise voltage regulation. It is appropriate for stepping down battery voltages to supply CPU cores and chipset components. Consider the integrated LDO controller if auxiliary low-noise rails are needed within the same system architecture.
