RT9218GS

Overview

The RT9218GS is a dual-output power management IC manufactured by Richtek USA Inc. It integrates one synchronous buck PWM DC-DC converter and one linear regulator within a single package. The device is designed to generate logic-supply voltages for PC-based applications. It operates with a switching frequency of 300kHz and is housed in a 14-SOP package with a width of 3.90mm.

Feature Summary

• Integrates a synchronous buck PWM DC-DC converter and a linear regulator for dual output power management.

Applications

• PC-based logic supply voltage generation

Procurement Notes

Verify the specific suffix 'GS' against the manufacturer's official datasheet to confirm pinout, thermal characteristics, and environmental compliance status. Ensure the 14-SOP package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact solution is required for generating multiple logic supply rails from a single input source. The integration of both switching and linear regulation allows for efficient power conversion alongside low-noise linear output capabilities suitable for sensitive digital logic circuits.

Part Context

This part belongs to the Richtek PMIC family focused on voltage regulation. It serves as a specialized controller for systems requiring combined high-efficiency switching and precise linear regulation, distinct from standalone buck or LDO regulators.

Replacement Considerations

Consult the official cross-reference list for verified substitutes. Ensure any replacement maintains the 14-SOP package and dual-output architecture without altering functional compatibility.
