Ground  
Ground  
Supply  
Ground for Internal Switching FET.  
Connect this pin at a single point to the power ground.  
Connect the battery between VIN and PGND. Bypass VIN with a 10 μF, 6.3 V or greater X5R/X7R  
capacitor.

Digital Input  
Digital Input  
Connect a 2.2 μH inductor between SW and the battery.  
This pin enables the torch, provided that the device is not in flash or assist light mode.  
Connect a digital signal to the TX_MASK pin. When the logic level is driven high during a flash  
event the current is reduced to the torch level.  
C1  
C2  
VOUT  
Output  
VOUT senses the output voltage of the boost converter and provides the input voltage to the LED  
current source. The VOUT pin features a comparator to detect an overvoltage condition if the LED  
string is open circuited. Connect a 10.0 μF capacitor between VOUT and PGND.  
STROBE  
Digital Input/ The STROBE input is used to synchronize the timing of the camera module to the LED driver in  
Output  
I2C-compatible interface mode. In 2-bit logic interface mode, this acts as an output, indicating the  
number of LEDs attached. STROBE = high indicates two LEDs, whereas STROBE = low indicates  
one LED.  
C3  
I2C/EN  
Digital Input  
Output  
A logic low selects the 2-bit logic interface, whereas logic high selects I2C-compatible interface. If  
I2C/EN is low and SDA/EN2 and SCL/EN1 are low, the driver enters shutdown mode with  
consumption < 1 μA.  
White LED Anode Connection. Connect LED_OUT to the anode of the white LED. LED_OUT is  
internally connected to a programmable PMOS current source, which regulates the LED current.  
D1  
D2  
LED_OUT  
SDA/EN2  
Digital Input/ Data Input/Output (SDA). In 2-bit logic interface mode, SDA/EN2 is the second input bit of the  
Output  
digital interface.  
Second Input Bit (EN2). In I2C mode, SDA is the data input/output of the I2C-compatible interface.  
D3  
SCL/EN1  
Digital Input  
Clock Input (SCL). In 2-bit logic interface mode, SCL/EN1 is the first input bit of the digital interface.  
First Input Bit (EN1). In I2C mode, SCL is the clock input of the I2C-compatible interface.
