When the input voltage is above the UVLO rising threshold and the EN pin is pulled to a voltage above 1.2 V, the TLV61070A is enabled and starts up. At the beginning, the TLV61070A charges the output capacitors with a current of about 185 mA when the output voltage is below 0.4 V. When the output voltage is charged above 0.4 V, the output current is changed to having output current capability to drive the 5-Ω resistance load. After the output voltage reaches the input voltage, the TLV61070A starts switching, and the output voltage ramps up further. The typical start-up time is 700 μs accounting from EN high to output, reaching target voltage for the application with input voltage is 2.5 V. Output voltage is 5 V, output effective capacitance is 10 μF, and no load. When the voltage at the EN pin is below 0.4 V, the internal enable comparator turns the device into Shutdown mode. In shutdown mode, the device is entirely turned off. The output is disconnected from the input power supply.
