7.4 Device Functional Modes

LMG3624 has two modes of operation that are controlled by the EN pin. The device is in active mode when the EN is logic high and in standby mode when the EN pin is logic low. In active mode, the IN pin controls the power FET. In standby mode, the IN pin is ignored, the GaN power FET is held off, and the AUX quiescent current reduces to the AUX standby quiescent current.
