Description
A1
PGND
Power Ground.
A2
SGND
Signal Ground.
A3
VIN
Input Voltage for the Device. Connect an input bypass capacitor very close to this pin.
B1
SW
Boost Switch. Connect the power inductor between SW and the input capacitor.
B2
GPIO
This pin enables the part to function in torch mode or functions as a TxMASK input, depending on the value set
using Bits[5:4] in Register 0x02 (see Table 14). When this pin is configured as a TxMASK input, the flash current is
using Bits[5:4] in Register 0x02 (see Table 14). When this pin is configured as a TxMASK input, the flash current is
reduced to the TxMASK current programmed in Register 0x07 (for LED1) and Register 0x0A (for LED2).
B3
EN
Enable. Set EN low to bring the quiescent current (I
Q
) to <1 µA. Registers are set to their default values when EN
is brought from low to high.
C1
VOUT
Boost Output. Connect an output bypass capacitor very close to this pin. This pin is the output for the 5 V
external voltage mode.
C2
STROBE
Strobe Signal Input. This pin synchronizes the flash pulse to the image capture. In most cases, this signal comes
directly from the image sensor.
C3
SDA

2
C Data Signal.
D1
LED1
Current Source for LED1. Connect this pin to the anode of flash LED1.
D2
LED2
Current Source for LED2. Connect this pin to the anode of flash LED2.
