„
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.
Drives 6 LED channels
Independent current on 3 pairs of LEDs
I2C serial interface programming
Adjustable current to 32mA in 0.5mA step
Power efficiency up to 91%
Fractional pump 1x/1.5x
Low noise input ripple
Fixed High Frequency Operation 1MHz
“Zero” Current Shutdown Mode
Soft start and current limiting
Short circuit protection
Thermal shutdown protection
Low noise and input ripple is achieved by operating at
a constant switching frequency of 1MHz which allows
the use of small external ceramic capacitors. The
1x/1.5x fractional charge pump supports a wide range
of input voltages from 3V to 5.5V with efficiency up to
91%, and is ideal for Li-Ion battery powered devices.
The LED channels are configured into three independent pairs, each containing 2 matched channels. Each
pair can be separately programmed from zero to 32mA,
2
in 0.5mA 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.

PIN FUNCTION
VIN is the supply pin for the charge pump. A small 1μF
ceramic bypass capacitor is required between the VIN
pin and ground near the device. The operating input
voltage range is from 2.2V to 5.5V. Whenever the input
supply falls below the undervoltage threshold (2V), all
LEDs channels will be automatically disabled.
GND is the ground reference for the charge pump. The
pin must be connected to the ground plane on the
PCB.
EN is the enable logic input for the driver. Guaranteed
levels of logic high and logic low are set at 1.3V and
0.4V respectively. When EN is initially taken high, the
device becomes enabled and all LED currents remain
at 0mA. To place the device into zero current shutdown
mode, the EN pin must be held low.
C2+, C2- are connected to each side of the 1μF
ceramic bucket capacitor C2.
C1+, C1- are connected to each side of the 1μF
ceramic bucket capacitor C1.
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.
SCL is the I2C serial clock input.
VOUT is the charge pump output that is connected to
the LED anodes. A small 1μF ceramic bypass
capacitor is required between the VOUT pin and
ground near the device.

BASIC OPERATION
LED CURRENT SETTING
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 I2C
serial interface and is stored in four
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
400µs) into 1.5x mode.
ƒ
RegA stores the LED current for group A
(LEDA1 and LEDA2 channels),
ƒ
RegB stores the LED current for group B
(LEDB1 and LEDB2 channels),
In 1.5x mode, the output is approximately equal to 1.5
times the input supply voltage (less any internal
voltage losses).
ƒ
RegC stores the LED current for group C
(LEDC1 and LEDC2 channels),
ƒ
RegEn selects the on/off state of each of the 6
LED channels.
8-bit registers RegA, RegB, RegC and RegEn as
follows:
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.

Characteristics subject to change without notice
At each write access to RegEn, the driver automatically
reconfigures to the mode (1x or 1.5x) that provides the
highest efficiency.

CAT3626
I2C INTERFACE
The LED driver is interfaced through a 2-wire serial
I2C-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 I2C 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 400kbit/s. The serial bit
sequence is shown below 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 I2C
address of the driver is internally fixed to the binary
value 1100110. The protocol requires that the start bit
and the device address are both repeated. For further
details on the I2C protocol, please refer to the I2C-Bus
Specification, document number 9398 393 40011, from
Philips Semiconductors.

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).
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 are programmable independently through the I2C
