Table 4. Pin functions
Pin number Name Function
1 Isense
Inverting input of the current loop op-amp. The pin is typically used for the
current control loop, connecting it to the positive end of the current sense
resistor through a decoupling resistor.
2GND
Ground. Return of the bias current of the device. 0 V reference for all
voltages. The pin has to be tied as close as possible to the ground output
terminal of the converter to minimize load current effect on the voltage
regulation setpoint.
