Table 3: System electrical parameters

3.10 System efficiency

Described here is the characterization of the power path from the battery supply (

VBAT) to the BUCK

output (

VOUTB) under different battery voltages, output voltages, and load current conditions.

In the following figure, the load current is swept from 1 µA to 150 mA and back to capture mode change

hysteresis.
