Undervoltage Lockout
An undervoltage lockout prevents the device from starting up and operating if the supply voltage at VIN is lower
than the programmed threshold shown in the electrical characteristics table. The device automatically shuts down
the converter when the supply voltage at VIN falls below this threshold. Nevertheless, parts of the control circuits
remain active, which is different than device shutdown using EN inputs. The undervoltage lockout function is
implemented to prevent device malfunction.
Overtemperature Shutdown
The device automatically shuts down if the implemented internal temperature detector detects a chip temperature
above the programmed threshold shown in the electrical characteristics table. It starts operating again when the
chip temperature decreases. A built-in temperature hysteresis avoids undefined operation caused by ringing from
overtemperature shutdown.
