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. 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. 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 I2C 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. 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. SDA is the I2C 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. SCL is the I2C serial clock input.
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 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. 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.

Figure 25. CAT3626 Functional Block Diagram
Basic Operation 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. 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.
LED Current Setting The LED current setting is programmed via the I2C 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), * 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.

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 400 kbit/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.
