RT8498GE

18V Multi-Topology LED Driver with Dimming Control
General Description
The RT8498 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 RT8498 provides
an internal soft-start function to avoid inrush current and
thermal shutdown to prevent the device from overheat.
The RT8498 is available in the SOT-23-6 package.
