RT8462GS

Overview

The RT8462GS is a DC-DC controller IC designed for LED driver applications, manufactured by Richtek USA Inc. It supports buck and boost topologies with an input voltage range of 4.5V to 36V. The device operates at a switching frequency between 100kHz and 1MHz. It features analog and PWM dimming capabilities and provides one output channel. The component is housed in a 14-SOP package (14-SOIC, 3.90mm width) without internal switches. It is rated for a junction temperature range of -40°C to 125°C.

Feature Summary

Supports both buck and boost converter topologies for flexible LED drive configurations
Enables precise brightness control through combined analog and PWM dimming interfaces
Operates within a wide input voltage range suitable for various power supply sources

Applications

LED backlighting systems
General LED lighting solutions

Procurement Notes

Verify component status as the RT8462GS is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary markets. Check datasheet revisions and PCN documents for any manufacturing changes. Ensure compatibility with existing PCB footprints and design requirements before sourcing.

Selection Notes

Select this component for designs requiring external switch buck-boost LED drivers. Consider the 14-SOP package size and thermal performance for the application environment. Evaluate the need for analog versus PWM dimming signals. Verify that the operating temperature range meets system specifications.

Part Context

This part belongs to the RT8462 family of LED driver controllers from Richtek. It is distinct from synchronous buck regulators like the RT8062 or other LED drivers such as the RT8474. The GS suffix indicates the specific package type and pin configuration used in this variant.
