RT8471GJ5 Description

Short technical summary and product information.

The RICHTEK RT8471GJ5 is a high-efficiency, continuous mode inductive step-down converter designed for driving series-connected LEDs. It operates from an input voltage range of 7V to 36V and utilizes hysteretic control with high-side current sensing to set the constant output current.

 

This LED driver IC includes an internal N-MOSFET with low RDS(ON) of 350mΩ. It supports an output current of 1A for the TSOT-23-5 package. LED brightness control is achieved via analog or PWM input signals, with a 300Hz on-board ramp generator. The device offers up to 97% efficiency and typical ±5% LED current accuracy.

 

Key features include input under-voltage lockout and thermal shutdown protection. The RT8471GJ5 is suitable for applications such as automotive LED lighting, high power LED lighting, indicator and emergency lighting, architectural lighting, low voltage industrial lighting, and signage and decorative LED lighting.

 

The RT8471GJ5 is available in a compact TSOT-23-5 package, designed for surface mount applications.
