LED Driver Operational Description
The LP5522 LED driver is constant current source. Current can be set with external resistor (R
) so that the current ratio between
resistor and LED is 1:400. R
ISET
current correlates to ISET reference voltage (V
ISET
). Consequently, current through LED can be
adjusted using equation I
OUT
ISET
.
Use of external resistor is optional. If external resistor is not connected, default output current is 5 mA. When external resistor is
not used ISET pin should be connected to VDD.
