RT8471ZSP Description

Short technical summary and product information.

The Richtek RT8471ZSP is a continuous mode inductive step-down converter designed for driving single or multiple series-connected LEDs. It operates from an input voltage range of 7V to 36V and features hysteretic control with high-side current sensing to set the constant output current.

 

This LED driver includes an internal N-MOSFET and supports both analog and PWM dimming for LED brightness control. It offers up to 97% efficiency and typical ±5% LED current accuracy. The RT8471ZSP is available in an 8-pin SOP package with an exposed pad for enhanced thermal dissipation.

 

Key specifications include an input voltage range of 7V to 36V, an output current of up to 1.2A, and a step-down (buck) topology. The operating temperature range is -40°C to 125°C (TJ). The device is suitable for surface mount applications.

 

Applications for the RT8471ZSP include automotive LED lighting, high power LED lighting, indicator and emergency lighting, architectural lighting, low voltage industrial lighting, and signage and decorative LED lighting.
