7.3 Feature Description

7.3.1 Thermal Shutdown

The TPS6024x device has a built-in thermal shutdown which turns off the power stage when the junction

temperature exceeds typical 160°C. When the junction temperature drops to typical 140°C, the device starts

switching again.

7.3.2 Current Limit

The TPS6024x device has a built-in overload protection which limits the output current.

7.4 Device Functional Modes

7.4.1 Start-up Procedure

The converter is enabled when EN is set from logic low to high. The start-up time to reach 90% of the nominal

output voltage is typically 0.5 ms at load currents lower than 10 mA and with an output capacitor of 1 µF.

7.4.2 Shutdown

Driving EN low disables the converter. This disables the internal circuits and reduces input current to typically 0.1

µA. In this mode, the load is disconnected from the supply voltage. The device exits shutdown once EN is set to

a high level.
