7.3.2 Enable and Disable

When the input voltage is above the maximal UVLO rising threshold of 1.8 V and the EN pin is pulled high, the TLV61046A is enabled. When the EN pin is pulled low, the TLV61046A goes into shutdown mode. The device stops switching and the isolation switch is turned off, providing the isolation between input and output. In shutdown mode, less than 1-µA input current is consumed.
