PRODUCTION DATA
The converter is in active mode whenever the EN/SYNC voltage is above the threshold voltage, VIN, is high enough to satisfy VIN_OPERATE, and no other fault conditions are present. The simplest way to enable operation is to connect EN/SYNC to VIN, which allows self start-up when the applied input voltage exceeds the minimum VIN_OPERATE.
In active mode, depending on the load current, input voltage, and output voltage, the converter is in one of five modes:
