Overview
The RT8471 is a high efficiency, continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs from a voltage source higher than the LED voltage. It operates from an input voltage of 7V to 36V and employs hysteretic control with a high side current sense resistor to set the constant output current. The RT8471 includes an output switch and a high side output current sensing circuit, which uses an external resistor to set the nominal average output current. LED brightness control is achieved with PWM dimming from an analog or PWM input signal. The RT8471 is available in a small TSOT-23-5 package or a more thermal efficient SOP-8 (Exposed Pad) and MSOP8 (Exposed Pad) packages.
