6.3.2 Enable and Disable

When the input voltage is above typical UVLO rising threshold of 1.7V and the EN pin is pulled high, the TLV61047-Q1 is enabled. When the EN pin is pulled low, the TLV61047-Q1 stops the PWM switch and turns off the low side switch. The EN pin has an internal pulldown resistance of 1MΩ. The device is disabled when the EN pin is floating. In shutdown mode, less than 0.4µA (typical) input current is consumed.
