CAT3626
6-Channel LED Driver with
I2Ct Interface
Description
The CAT3626 is a high efficiency 1x/1.5x fractional charge pump
with programmable dimming current in six LED channels. To ensure
uniform brightness in LCD backlight applications, each LED channel
delivers an accurate regulated current.
http://onsemi.com
Low noise and input ripple is achieved by operating at a constant
switching frequency of 1 MHz which allows the use of small external
ceramic capacitors. The 1x/1.5x fractional charge pump supports a
wide range of input voltages from 3 V to 5.5 V with efficiency up to
91%, and is ideal for Li−Ion battery powered devices.

CASE 510AE
The LED channels are configured into three independent pairs, each
containing 2 matched channels. Each pair can be separately
programmed from zero to 32 mA, in 0.5 mA resolution steps, using

the I C serial interface. Any individual channel can be disabled while
others remain active. When the enable input (EN) is low, the device is
in shutdown mode drawing zero current.
The device is available in a 16−pad TQFN package with a max
height of 0.8 mm.

Pin Function
VIN is the supply pin for the charge pump. A small 1 mF
ceramic bypass capacitor is required between the VIN pin
and ground near the device. The operating input voltage
range is from 2.2 V to 5.5 V. Whenever the input supply falls
below the undervoltage threshold (2 V), all LEDs channels
will be automatically disabled.
VOUT is the charge pump output that is connected to the
LED anodes. A small 1 mF 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 1 mF ceramic
EN is the enable logic input for the driver. Guaranteed levels
of logic high and logic low are set at 1.3 V and 0.4 V
respectively. When EN is initially taken high, the device
becomes enabled and all LED currents remain at 0 mA. To
place the device into zero current shutdown mode, the EN
pin must be held low.
bucket capacitor C1.
C2+, C2− are connected to each side of the 1 mF ceramic
bucket capacitor C2.
LEDxx provide the internally regulated current to the six
LED cathodes. These pins enter a high−impedance
zero−current state whenever the device is placed in
shutdown mode. In applications using less than six LEDs,
the unused channels should be disabled through the RegEn
register.
2
SDA is the I C serial data line. This is a bidirectional line
allowing data to be written into and read from the four
registers in the driver. Registers RegA/B/C set the LED
current in each pair of channels, while RegEn sets the
On/Off state independently of each channel.
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.
2
SCL is the I C serial clock input.

Basic Operation
LED Current Setting
2
At power−up, the CAT3626 starts operating in 1x mode
where the output will be approximately equal to the input
supply voltage (less any internal voltage losses). If the
output voltage is sufficient to regulate all LEDs currents the
device remains in 1x operating mode.
The LED current setting is programmed via the I C serial
interface and is stored in four 8−bit registers RegA, RegB,
RegC and RegEn as follows:
• RegA stores the LED current for group A (LEDA1 and
LEDA2 channels),
If the input voltage is insufficient or falls to a level where
the regulated currents cannot be maintained, the device
automatically switches (after a fixed time of 400 ms) into
1.5x mode.
In 1.5x mode, the output is approximately equal to 1.5
times the input supply voltage (less any internal voltage
losses).
The above sequence is repeated each and every time the
chip is either powered−up or taken out of shutdown (via
EN pin), or the RegEn register is accessed by write cycle.
• RegB stores the LED current for group B (LEDB1 and
LEDB2 channels),
• RegC stores the LED current for group C (LEDC1 and
LEDC2 channels),
• RegEn selects the on/off state of each of the 6 LED
channels.
At each write access to RegEn, the driver automatically
reconfigures to the mode (1x or 1.5x) that provides the
highest efficiency.

I C Interface
The LED driver is interfaced through a 2−wire serial
for read and write operations into the registers. Read and
write instructions are initiated by the master controller/CPU
and acknowledged by the slave LED driver. The I C address

I C−bus in order to control the state and the current in each
of the six LED channels. The SDA and SCL lines comply
with the I C electrical specification and should be
terminated with pull−up resistors. When the bus is not used,
both lines are high. The device supports the maximum bus
speed of 400 kbit/s. The serial bit sequence is shown below
of the driver is internally fixed to the binary value 1100110.
The protocol requires that the start bit and the device address

CAT3626
Typical Application
The CAT3626 is ideal for driving RGB (red green blue)
LEDs with common anode configuration. The individual
LED currents associated with the red, green and blue LEDs
allowing to generate an accurate color mixing. Dimming
while maintaining the same color can be done by
reprogramming the RegEn register on and off with the
appropriate duty cycle (PWM mode).
