PRODUCTION DATA
The internal LDO has a lower enable threshold than the output of the converter. When the EN/SYNC pin voltage is above 1.1 V (maximum) and below the precision enable threshold, the internal LDO regulates the VCC voltage at 3.3 V typical. The precision enable circuitry is ON after VCC is above its UVLO. The internal power MOSFETs remain off unless the voltage on EN/SYNC goes above its precision enable threshold. The converter also employs UVLO protection. If the VCC voltage is below its UVLO level, the output of the converter is turned off.
