unless otherwise noted.)
Note 1: Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 100mV below its nom-
Note 2: V
Note 3: Minimum pulse width required to guarantee proper dimming operation.
Note 4: FAULT multiplexes a programming interface and fault indication functionality. At power-up initialization, an internal timer
Note 5: Not production tested. Guaranteed by design.
Note 6: Recovery time is the time required for FAULT to be pulled high by the internal 10kΩ resistor.

enables FAULT and two programming passcodes must be entered within the programming slot to enter programming
mode. If the programming passcodes are not received correctly within the programming slot, FAULT goes back towards
fault indication. Cycling power to the device is required to re-attempt entry into programming mode.
