Table 4. Pin functions
Pin number Name
Function
Inverting input of the current loop op-amp. The pin is typically used for the
1
Isense current control loop, connecting it to the positive end of the current sense
resistor through a decoupling resistor.
Ground. Return of the bias current of the device. 0 V reference for all
2
GND
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.
