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 5mA load. Maximum output load is the

maximum load at which measured output voltage is no lower than 50mV from the original 5mA load measured voltage.

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