6.3.6 Enable and Disable

When the input voltage is above UVLO rising threshold and the EN pin is pulled to high voltage, the TPS61299-Q1 is enabled. When the EN pin is pulled to low voltage, the TPS61299-Q1 goes into true shutdown mode. . In true shutdown mode, the device stops switching and the high-side MOSFET fully turns off, providing the completed disconnection between input and output. Less than 60nA input current is consumed in shutdown mode.
