Description
Input voltage for the charge pump. Decouple with 4.7μF ceramic capacitor close to the
pins of the IC.
Positive input for the external fly capacitor. Connect a ceramic 1μF capacitor close to
the pins of the IC.
Negative input for the external fly capacitor. Connect a ceramic 1μF capacitor close to
the pins of the IC.
Logic input to toggle between FLASH and TORCH mode. In TORCH Mode FB is regulated
to the internal 50mV reference. In FLASH Mode FB reference voltage can be adjusted by
changing the resistor from R SET pin to ground. Choose the external current sense
Resistor (R SENSE ) based on desired current in TORCH Mode.
Shutdown control input. Connect to V IN for normal operation, connect to ground for
shutdown.
Connect a resistor from this pin to ground. When in FLASH Mode (FLASH = High) this
resistor sets the current regulation point according to the following:
V FB = (1.26V/R SET )*11.2K ?
Feedback input for the current control loop. Connect directly to the current sense
resistor.
Internal ground pin. Control circuitry returns current to this pin.
Power ground pin. Fly capacitor current returns through this pin.
Charge Pump Output Voltage. Decouple with an external capacitor. At least 1μF is
recommended. Higher capacitor values reduce output ripple.
