Under-voltage Lockout

The TPS61299-Q1 has a built-in under-voltage lockout (UVLO) circuit to ensure the device working properly. When the input voltage is above the UVLO rising threshold of 0.7V, the TPS61299-Q1 can be enabled to boost the output voltage. After the TPS61299-Q1 starts up and the output voltage is above 1.8V, the TPS61299-Q1 can work with the input voltage as low as 0.5V.
