AC Electrical Characteristics - LED Driver
VCCT = 3.05 to 3.55V or 4.7 to 5.5V, TA = -40°C to +95°C, unless otherwise noted.
Typical values are VCC = 3.3V, IPBOUT = 4mA, IMOD = 50mA.

NOTES:
1. Minimum voltage at OUTP > 0.7 V; LED forward voltage and total series resistance must be considered if output is DC coupled to LED.
2. Default if TCSTART is floating.
