RT8474AGSP Description

Short technical summary and product information.

The RICHTEK RT8474AGSP is a current-mode LED driver IC suitable for various lighting applications, including desk lights, room lighting, and industrial display backlights. It supports a wide input voltage range from 4.5V to 50V and an output voltage up to 50V.

 

This device features an internal 2A power switch and operates at a fixed 500kHz switching frequency, allowing for smaller external components. LED dimming can be controlled via analog or PWM signals. The RT8474AGSP includes an internal soft-start function to prevent inrush current and thermal shutdown for overheat protection.

 

It is available in a surface-mount 8-SOP-EP package. The operating temperature range is -40°C to 85°C (TA).

 

Key electrical specifications include an input voltage range of 4.5V to 50V, an output voltage up to 50V, and an output current of 2A. The topology is a step-down (buck) regulator with one output.
