RT8476GSP

Overview

The RT8476GSP is a single-output DC-DC controller designed for LED driver applications, manufactured by Richtek USA Inc. It supports both step-down (buck) and step-up (boost) topologies within a single device. The component operates with an input voltage range up to 50V and features analog and PWM dimming capabilities for precise light control. Packaged in an 8-SOP-EP format with an exposed pad for thermal management, it is rated for operation across a temperature range of -40°C to 85°C.

Feature Summary

Supports buck and boost converter topologies for flexible LED drive configurations
Enables precise brightness control through combined analog and PWM dimming interfaces
Integrated exposed pad design facilitates efficient thermal dissipation

Applications

LED backlighting systems
General solid-state lighting fixtures
Automotive interior illumination

Procurement Notes

Verify the specific suffix 'GSP' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Confirm availability as this part may be subject to end-of-life notices or discontinuation. Ensure the ordering documentation matches the exact 8-SOP-EP specification required for your PCB layout.

Selection Notes

Select this component when a single IC must handle both buck and boost operations for varying input voltages. It is suitable for designs requiring high input voltage tolerance up to 50V. Consider the exposed pad requirement for thermal performance and verify that the 8-SOP-EP footprint aligns with the target assembly process.

Part Context

This device belongs to the RT847x series of LED drivers from Richtek. It shares functional similarities with parts like the RT8477A but differs in specific topology support and package options. It serves as a specialized power management solution for driving LEDs where input voltage fluctuates significantly relative to the LED string forward voltage.
