SLIS178B October 2017 – January 2018 TPS92830-Q1
The TPS92830-Q1 device has a linear analog input pin, ICTRL, for output-current dimming. Voltage across the sense resistors is linearly reduced if the ICTRL input voltage V(ICTRL) decreases. Analog dimming can be used for brightness control, LED bin brightness correction, and thermal protection with a thermistor. ICTRL also supports off-board connection for LED binning and thermistor connection.
