PIN FUNCTION
V IN is the supply pin for the charge pump. A small
1 μ F ceramic bypass capacitor is required between
the V IN pin and ground near the device. The
operating input voltage range is from 2.7 V to 5.5 V. If
V IN falls below the under-voltage threshold, all LED
channels disable and the device enters shutdown
mode.
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 1.4 V and
0.4 V respectively. When EN/SET is initially taken
high, the device becomes enabled and all LED
currents remain at 0 mA. To start LED current, device
should be in PWM mode (See p. 5). To place the
device into zero current mode, the EN/SET pin must
be held low for more than 50 ms.
V OUT is the charge pump output that is connected to
the LED anodes. A small 2.2 μ F ceramic bypass
capacitor is required between the V OUT 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
flying capacitor C1
LEDA, LEDB provides the internal regulated current
source for each of the LED cathodes. These pins
enter high-impedance zero current state whenever
the device is in shutdown mode.
PAD is the exposed pad underneath the packag e.
For best thermal performance, the pad should be
soldered to the PCB and connected to the ground
plane
