RT8452GS

Overview

The RT8452GS is a DC-DC controller IC designed for LED driver applications, manufactured by Richtek USA Inc. It supports buck and boost topologies with one output. The device operates within an input voltage range of 4.5V to 36V and provides an output voltage up to 48V. It features a switching frequency of 350kHz and supports both analog and PWM dimming methods. The component is housed in a 16-SOIC package (0.154" width) and is rated for a junction temperature range of -40°C to 125°C.

Feature Summary

Supports step-down (buck) and step-up (boost) converter topologies for flexible LED driving configurations.
Enables precise light control through integrated analog and pulse-width modulation (PWM) dimming capabilities.
Operates with a wide input voltage range suitable for various power supply sources.

Applications

LED backlighting systems
General solid-state lighting fixtures

Procurement Notes

Verify the specific suffix 'GS' against the manufacturer's official datasheet to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as per the latest environmental declaration. Check for product change notices regarding packaging or material composition updates before finalizing procurement specifications.

Selection Notes

Select this component when designing single-output LED drivers requiring buck or boost conversion. Ensure the application demands a 350kHz switching frequency and compatible dimming interfaces. Verify that the 16-SOIC footprint fits the PCB layout constraints and that the thermal requirements align with the specified junction temperature limits.

Part Context

This part belongs to the RT8462 family of LED driver controllers from Richtek. While similar in function, the RT8452GS utilizes a 16-SOIC package compared to the 14-SOP variant found in other models. It serves as a dedicated power management solution for high-efficiency lighting applications.
