SLVUCT6 February 2024 TPS61299
The TPS61299 has a built-in under-voltage lockout (UVLO) circuit to make sure the device working properly. When the input voltage is above the UVLO rising threshold of 0.7V, the TPS61299 can be enabled to boost the output voltage. After the TPS61299 starts up and the output voltage is above 1.8V, the TPS61299 can work with the input voltage as low as 0.5V.
