PRODUCTION DATA
The VIN undervoltage lockout (UVLO) protection monitors the VCC pin voltage to protect the internal circuitry from low input voltage. When the VCC voltage is lower than the UVLO threshold voltage, the device shuts off and outputs are discharged to prevent mis-operation of the device. The converter begins operation again when the input voltage exceeds the threshold by a hysteresis of 500 mV (typical). This is a non-latch protection.
