RT8471GSP

Overview

The RT8471GSP is a high-brightness LED driver IC manufactured by Richtek USA Inc., designed for hysteretic control applications. It operates with an input voltage range of 4.5V to 50V and supports output currents up to 2A. The device features adjustable switching frequency and includes protection mechanisms such as over-voltage, over-current, and thermal shutdown. Packaged in an 8-SOP-EP (SOIC) format with exposed pad for enhanced thermal performance, it functions within a temperature range of -40°C to 85°C.

Feature Summary

Hysteretic control architecture for fast transient response
Integrated power switch for compact design
Comprehensive protection against over-voltage, over-current, and thermal overload

Applications

High-brightness LED lighting systems
Backlight drivers for displays
General LED illumination applications

Procurement Notes

Verify the specific suffix 'GSP' corresponds to the 8-SOP-EP package variant when sourcing. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCN) or End-of-Life (EOL) announcements from Richtek Technology Corporation prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring simple hysteretic regulation without external compensation networks. Ensure the application's input voltage does not exceed the 50V maximum rating. Consider the thermal dissipation requirements of the 8-SOP-EP package if operating near the 2A current limit.

Part Context

This part belongs to Richtek's LED driver portfolio, specifically utilizing hysteretic control technology. It is distinct from PWM-controlled counterparts like the RT8474A or RT8477A series. The GSP suffix denotes the specific surface-mount package configuration used for thermal management.
