Compensation pin. A compensation cap (4700pF to 1µF) is normally connected between this pin and
SGND.
Control pin for dimming and shut-down. A voltage between 250mV and 5.5V controls the brightness,
and less than 100mV shuts down the converter.
Output voltage sense. Use for over voltage protection.
Inductor connection pin. The drain of internal MOSFET.
Power Ground pin. The source of internal MOSFET.
Signal Ground. Ground pin for internal control circuitry. Needs to connect to PGND at only one point.
Current sense pin. Connect to sensing resistor to set the LED bias current.
Power supply for internal control circuitry.
