Richtek EVB_RT8498GE

1A3V4.5V~18V

Overview

The RT8498GE is a current-mode LED driver supporting wide input voltage range from 3V to 18V and output voltage up to 18V. With internal 350kHz operating frequency, the size of the external PWM inductor and input/output capacitors can be minimized. High efficiency is achieved by a 100mV current sensing control. LED dimming control can be done from either analog or PWM signal. The RT8498GE provides an internal soft-start function to avoid inrush current and thermal shutdown to prevent the device from overheat. The RT8498GE is available in the SOT-23-6 package.
