The RT9302 is a high performance constant current driver
for white LED. It supports up to 3 white LEDs and regulates
a constant current for uniform intensity. Each channel
supports up to 20mA output current with 1% typical current
accuracy and 0.7% typical current matching. The RT9302
provides a 16-step brightness dimming control. The LED
current can be easily configured from 1.25mA to 20mA.
The dimming of white LEDs' current can be achieved by
applying a pulse signal to the EN pin. The LED current
can be turned off by EN pin with pull low for 20μs or longer.
The typical leakage current is 4μA while shutdown
condition.
RT9302 is available in a TSOT-23-8 package (1.0mm
maximum height).
