RT8474

High Voltage Multiple-Topology LED Driver

RT8474 Features

* High Voltage : VIN Up to 50V, VOUT Up to 50V

* Support Multiple-Topologies (Buck / Boost / Buck- Boost)

* Built-In 2A Power Switch

* Current-Mode PWM Control

* 500kHz Fixed Switching Frequency

* Analog or PWM Control Signal for LED Dimming

* Internal Soft-Start to Avoid

RT8474 General Description

The RT8474 is a current-mode LED driver supporting wide input voltage range from 4.5V to 50V and output voltage up to 50V. With internal 500kHz operating frequency, the size of the external PWM inductor and input/output capacitors can be minimized. High efficiency is achieved by a 100mV current sens.
