Function
Input Voltage. Input range: 2.7V to 5.5V.
TORCH/FLASH Pin. Low = Torch Mode, High = Flash Mode
Switch Pin
Over Voltage Protection Pin
Compensation network connection. Connected to the output of the voltage error amplifier.
Shutdown pin logic input. High = Shutdown, Low = Enabled
Enable pin logic input. High = Enabled, Low = Shutdown
Flash Timeout. External capacitor determines max. duration allowed flash pulse
Soft Start Pin
Feedback Pin
Torch FET Drain
Flash FET Drain
Ground
Analog Ground. Connect the ground of the compensation components, C
FTO
and soft start
cap to AGND. AGND must be connected to the GND pin through a low impedance
connection.
