All voltages are with respect to the potential at the GND pin.
Min and Max limits are specified by design, test, or statistical analysis. Typical (typ.) numbers represent the most likely norm. Unless
otherwise specified, conditions for typ. specifications are: V BATT = 3.6V and T A = 25°C.
The parameters in the electrical characteristic table are tested at V BATT = 3.6V unless otherwise specified. For performance over the
input voltage range refer to datasheet curves.
The input voltage range recommended for ideal applications performance for the specified output voltages is given below:V BATT = 2.7V
to 5.5V for 1.0V ≤ V OUT_DCDC < 1.8VV BATT = (V OUT_DCDC + 1V) to 5.5V for 1.8V ≤ V OUT_DCDC < 3.6V
Electrical Characteristic table reflects open loop data (FB = 0V and current drawn from SW pin ramped up until cycle by cycle current
limit is activated). Closed loop current limit is the peak inductor current measured in the application circuit by increasing output current
until output voltage drops by 10%.
