Output Pin Description
Pin 1, GND, the signal and power ground. Connect the negative power supply terminal to this pin.
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 0.022.
Pin 3, VPSDR, the power supply positive input. Connect the positive power supply terminal to this pin. When
using this pin, the power supply current will not be monitored and the controller will not be
turned off when the power supply current exceeds 2.27A. The efficiency will be higher by using
this pin since the power supply current does not go through the 0.022resistor, as opposed to
using Pin 2.
Pin 4, LIS,
analog input control voltage. Setting this voltage by using a POT (Potentiometer) or a DAC
from 0 to 1.25V will set the output current from 0 to 1A. The input impedance of this pin is
100K. Leaving this pin float will allow the POT on the PCB to set the output current which
sets the output current from 0 to 1A, turning clock-wise to increase the current.
Pin 5, 2.5V, analog output, reference voltage, 20ppm/°C, ± 1mA.
Pin 6, SDNG, digital input, shut down negative logic, 0 to 0.8V = shut down; 2V to 5V = turn on. Leaving this
pin open will enable the controller.
Pin 7, PSIO,
analog output, power supply current indication. It will be effective when connecting the positive
power supply terminal through VPSPR (Pin 2).
Power supply current = [voltage at PSIO]*0.91. For example, when the output voltage is 2V,
the power supply current = 2*0.91 = 1.82A.
Pin 8, LEDA, analog output for LED anode. Connect this pin to the LED positive terminal, the anode.
Pin 9, GND, power ground, connect this pin to the LED negative terminal, the cathode.
