Note:

1. VBOOST is the voltage applied to the inductor attached to the LA2 pin in boost modes.

2. It is permissible for the input voltage to exceed the output voltage by ~0.3V in boost configurations, using the TOFF max limiting

feature. Refer to the boost mode TOFF maximum limiting section of the datasheet.

3. Maximum output load current is determined by first measuring the output voltage with a 1.25mA load. Maximum output load is the

maximum load at which measured output voltage is no lower than 50mV from the original 1.25mA load measured voltage.

4. In boost bootstrap mode, the DCDC current limit is enabled and VOA will not be tightly regulated. Peak load currents are expec-

ted to be primarily sourced from the VOA output capacitor, and the VOA output is expected to droop under load and allowed

sufficient time to recover before the next peak load is applied. The maximum output current specification can be interpreted here

as the maximum allowed DC current before the VOA output may begin to droop, or as the maximum allowed average current.

5. For converters enabled by default, total startup time will be TSTART + TBOOT (found in the General Operating Conditions table)
