RT8474AGSP

Overview

The RT8474AGSP is a high-voltage buck LED driver IC manufactured by Richtek USA Inc. It features an integrated internal switch capable of handling 2A output current and supports a maximum supply voltage of 50V. The device operates at a switching frequency of 500kHz and accepts input voltages between 4.5V and 50V. It offers analog and PWM dimming capabilities for precise brightness control. The component is housed in an 8-SOP-EP package with exposed pad for thermal management, suitable for surface mount installation across a temperature range of -40°C to 85°C.

Feature Summary

Integrates a high-voltage internal power switch for compact design
Supports both analog and pulse-width modulation dimming methods
Operates as a step-down DC-DC converter topology

Applications

LED backlighting systems
General LED lighting applications

Procurement Notes

Verify the End-of-Life (EOL) status before procurement, as official records indicate this product reached end-of-life on September 9, 2025. Confirm availability through authorized distributors or secondary market channels. Ensure compatibility with existing PCB footprints for the 8-SOP-EP package. Check RoHS3 compliance documentation if required for specific regulatory environments.

Selection Notes

Select this component for designs requiring high input voltage tolerance up to 50V without external level shifting. The fixed 500kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the exposed pad thermal requirements for heat dissipation in enclosed spaces. Verify that the 2A switch current rating meets the peak load requirements of the target LED string configuration.

Part Context

This part belongs to the RT8474 family of high-voltage LED drivers from Richtek. It is specifically designed for applications where direct connection to higher voltage rails is necessary. The AGSP suffix denotes the specific tape and reel packaging variant within the SOP-8EP footprint family.
