DEVICE INFORMATION  
Table 2. PIN FUNCTIONS  
PIN  
I/O  
DESCRIPTION  
NAME  
AVIN  
NO.  
E4  
A2  
E2  
E1  
E3  
B4  
I
O
I
This is the input voltage pin of the device. Connect directly to the input bypass capacitor.  
This is the output voltage pin of the converter.  
VOUT  
LED1  
LED2  
LED3  
STRB0  
LED return input (current sinks). This feedback pin regulates the LED current through the internal sense  
resistor by regulating the voltage across it. Connect to the cathode of the white LEDs.  
I
I
I
LED1/2/3 enable logic input. This pin can be used to enable/disable the high-power LEDs connected to the  
device.  
STRB0 = LOW: LED1, LED2 and LED3 current regulators are turned off.  
STRB0 = HIGH: LED2, LED2 and LED3 current regulators are active. The LED current level (video light or  
flash current) is defined according to the STRB1 logic level.  
NRESET  
B3  
I
I
Master hardware reset input.  
NRESET = LOW: The device is forced in shutdown mode and the I2C control I/F and all internal control  
registers are reset.  
NRESET = HIGH: The device is operating normally under the control of the I2C interface.  
SCL  
B2  
B1  
D4  
Serial interface clock line. This pin must not be left floating and must be terminated.  
SDA  
I/O Serial interface address/data line. This pin must not be left floating and must be terminated.  
GPIO/PG  
I/O This pin can either be configured as a general purpose input/output pin (GPIO) or either as an open-drain or  
a push-pull output to signal when the converters output voltage is within the regulation limits (PG). Per  
default, the pin is configured as an open-drain power-good output.  
TS  
C4  
I
NTC resistor connection. This pin can be used to monitor the LED temperature. Connect a 220kNTC  
resistor from the TS input to ground. In case this functionality is not desired, the TS input should be tied to  
AVIN or left floating.  
INDLED  
STRB1  
A1  
D3  
O
I
This pin provides a constant current source to drive low VF LEDs. Connect to LED anode.  
LED current level selection input. Pulling this input high disables the video light watchdog timer.  
STRB1 = LOW: flash mode is enabled.  
STRB1 = HIGH: video light mode is enabled.  
Tx-MASK  
SW  
C3  
I
RF PA synchronization control input. Pulling this pin high turns the LED from flash to video light operation,  
thereby reducing almost instantaneously the peak current loading from the battery.  
C1  
C2  
I/O Inductor connection. Drain of the internal power MOSFET. Connect to the switched side of the inductor. SW  
is high impedance during shutdown.  
PGND  
AGND  
D1  
D2  
Power ground. Connect to AGND underneath IC.  
A3  
A4  
Analog ground.
