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.
