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.
