This COMP2_MAIN command contains 3 fields for configuring the internal integration circuit and the ramp generation circuit. See Loop Compensation for more details.
The INT_GAIN bits select the gain of the integration stage.
The INT_TIME bits set the time constant of the integration stage which affects the settling and response time following an output voltage error.
The RAMP bits select the amplitude of the internal-generated ramp.
Return to Supported I2C and Default Values.
