PRODUCTION DATA.
The undervoltage lockout (UVLO) protection monitors the VCC pin voltage to protect the internal circuitry from low input voltages. When the voltage is lower than UVLO threshold voltage, the under-voltage lockout circuit prevents mis-operation of the device by turning off both high-side and low-side MOSFETs. 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.
