Pin 1, GND, the signal and power ground. Connect the negative power supply terminal to this pin. LED22V1A 7V to 22V 1V to power supply voltage – 0.5V 1A 90% typical 0 to 1.25V FR-4 PCB −10° C to 85° C 25mm × 14mm × 5.5mm Pin 2, VPSPR, the power supply positive input. Connect the positive power supply terminal to this pin. When using this pin, the power supply current will be monitored (See Pin 7) and the controller will be turned off when the current exceeds 2.27A. The current sense resistor is of 0.022Ω . Pin 3, VPSDR, the power supply positive input. Connect the positive power supply terminal to this pin. The efficiency will be higher by using this pin since the power supply current does not go through the 0.022Ω resistor, as opposed to using Pin 2.
