PIN FUNCTION
VIN
is the supply pin for the charge pump. A small
1
μ
F ceramic bypass capacitor is required between the
VIN pin and ground near the device. The operating
input voltage range is from 2.5V to 5.5V. Whenever
the input supply falls below the under-voltage
threshold (2V) all the LED channels will be
automatically disabled and the device register are
reset to default values.
EN/SET
is the enable and one wire addressable
control logic input for all LED channels. Guaranteed
levels of logic high and logic low are set at 1.3V and
0.4V respectively. When EN/SET is initially taken
high, the device becomes enabled and all LED
currents remain at 0mA. To place the device into zero
current mode, the EN/SET pin must be held low for
more than 1.5ms.
VOUT
is the charge pump output that is connected to
the LED anodes. A small 1
μ
F ceramic bypass
capacitor is required between the VOUT pin and
ground near the device.
GND
is the ground reference for the charge pump.
The pin must be connected to the ground plane on the
PCB.
C1+, C1-
are connected to each side of the ceramic
bucket capacitor C1.
C2+, C2-
are connected to each side of the
ceramic bucket capacitor C2.
LEDxx
provide the internal regulated current for
each of the LED cathodes. These pins enter high-
impedance zero current state whenever the device
is placed in shutdown mode.
TAB
is the exposed pad underneath the package.
For best thermal performance, the tab should be
soldered to the PCB and connected to the ground
plane.
