Description
SC606
Low Noise Smart LED
Driver with Swewwr.iDaatlaSIhneett4eU.rcfomace
Features
The SC606 is a very high efficiency charge pump white/color LED
driver from the mAhXLifeTM family of products. It is optimized for
Li-Ion battery applications. The LED current is regulated to a value
configured by the user through an I2C compatible serial interface.
LED outputs are current-matched for consistent LED brightness.
Up to 6 LEDs are controlled in three zones for brightness control in
multiple displays. The 6 LED outputs are divided into 3 pairs of
LEDs. Each pair has current that is programmable independent of
the other pairs. Any combination of LEDs may be turned on using
the serial interface. The SC606 also has a float detect feature
that disables any current driver during normal operation when an
open-load condition is detected.
Patented low noise switching circuitry and constant output current
allow the use of extremely small input and output capacitors.
Very High Efficiency Over 90% of Battery Life
Current Regulation for 6 LEDs
Current Matching Tolerance of +/- 3.5% from LED to LED
Current Accuracy to +/- 6.5% of Specified Value
Current Range per LED [0.5mA - 32mA]
High Available Total LED Current = 6 ILED = 120mA
I2C Bus Limited Compatibility SC606
Low Shutdown Current: 0.1μA Typical

Pin Descriptions
Pin Pin Name Pin Function
1
ILEDA1
Current sink for LEDA1 (lf not in use, pin may be left open or grounded).
2 SDA Bi-directional serial data line.
3 SCL Serial bus clock input.
4 EN Active high enable. Bias current is typically 0.1μF when EN is low.
5
VOUT
Output of the charge pump. Connect a 1μF capacitor from VOUT to ground.
6
VIN
Input voltage. Connect a 1μF capacitor from VIN to ground. For improved performance
when using 250 kHz and 1.5x mode, increase the capacitor to 4.7μF ~ 10 μF.
7 C1- Negative terminal of bucket capacitor 1.
8 C1+ Positive terminal of bucket capacitor 1.
9 C2- Negative terminal of bucket capacitor 2.
10 C2+ Positive terminal of bucket capacitor 2.
11
GND
Ground.
12
ILEDC2
Current sink for LEDC2 (lf not in use, pin may be left open or grounded).
13
ILEDC1
Current sink for LEDC1 (lf not in use, pin may be left open or grounded).
14
ILEDB2
Current sink for LEDB2 (lf not in use, pin may be left open or grounded).
15
ILEDB1
Current sink for LEDB1 (lf not in use, pin may be left open or grounded).
16
ILEDA2
Current sink for LEDA2 (lf not in use, pin may be left open or grounded).
T
Thermal Pad
Pad for heat sinking purposes. Connect to ground plane using multiple vias.
