operation, this pin represents the output of the error amplifier. Use COMP/EN in combination with the
FB pin to compensate for the voltage control feedback loop of the converter. Pulling COMP/EN low

and the high-side gate and low-side gate of the MOSFETs outputs to be held low. The external
pull-down device will initially need to overcome a maximum of 5mA of COMP/EN output current.
However, once the controller is disabled, the COMP/EN output will also be disabled, thus only a 20µA
current source will continue to draw current. Range: 0V to 5V.
The FB pin is the output voltage adjustment of the ISL8204M, ISL8206M. It will regulate to 0.6V at the FB
pin with respect to the PGND pin. The ISL8204M, ISL8206M has an integrated voltage dividing resistor. This
is a precision 9.76kΩ resistor (RFB-TI) between the VOUT and FB pins. Different output voltages can be
programmed with additional resistors between FB to PGND. Range: 0.6V.
