RT8474A |
The RT8474A is a current-mode LED driver supporting wide
input voltage range from 4.5V to 50V in multiple topologies.
With the 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 sensing control. LED dimming control can be done
from either analog or PWM signal. The RT8474A provides
an internal soft-start function to avoid inrush current and
thermal shutdown to prevent the device from overheat.
The RT8474A is available in the SOP-8 (Exposed pad)
package. |
