Note1: The min. operating voltage is dependent on the duty cycle.
Note2: The dropped output voltage is that the input power (VIN pin) is switched to battery power (LX pin),
when the VIN power is removed.
Note3: Device is boostrapped ( power to the IC comes from OUT). This correlates directly with the actual
battery supply.
Note4: If the LDO mode is used, the output voltage should be under 3.8V.
