RT8456GE

Overview

The RT8456GE is a linear LED driver IC manufactured by Richtek USA Inc., designed for single-output applications. It operates within a supply voltage range of 4.75V to 48V and supports dimming control. The device features an internal switch and is housed in a SOT-23-6 surface-mount package. It is rated for operation at junction temperatures between -40°C and 125°C. This component is classified as a linear regulator type with one output channel.

Feature Summary

• Linear regulation architecture for precise current control
• Integrated internal switching capability
• Supports analog or PWM dimming functions

Applications

• LED lighting systems
• General illumination circuits
• Backlight drivers

Procurement Notes

Verify the specific suffix GE against official datasheets to confirm pinout and thermal characteristics. Confirm end-of-life status, as this part may be discontinued. Check RoHS compliance declarations for environmental requirements. Ensure compatibility with existing PCB footprints for the SOT-23-6 package before ordering.

Selection Notes

Select this component for low-noise linear LED driving where input voltages up to 48V are available. Consider thermal management due to linear dissipation. Verify that the required operating temperature range extends to 125°C junction temperature. Compare against switching alternatives if efficiency is critical.

Part Context

This part belongs to the RT8456 series of LED drivers from Richtek. It is distinct from switching regulators like the RT8477A. The GE suffix denotes the specific package variant. It serves as a power management IC for steady-state LED current regulation.
