2.1 Power Requirements

The TPSM81299 has a built-in undervoltage lockout (UVLO) circuit to make sure the device working properly. When the signal input voltage(AVIN) is above the UVLO rising threshold of 0.7V, the TPSM81299 can be enabled to boost the output voltage. After the TPSM81299 starts up and the output voltage is above 1.8V, the TPSM81299 can work with the signal input voltage (AVIN) as low as 0.5V.
