The inductor selected must have a saturation current rating greater than or equal to the calculated IPEAK. Due to

the high currents possible with the bq2416xx, a thermal analysis must also be done for the inductor. Many

inductors have a 40°C temperature-rise rating. The DC component of the current can cause a 40°C temperature

rise above the ambient temperature in the inductor. For this analysis, the typical load current may be used

adjusted for the duty cycle of the load transients. For example, if the application requires a 1.5A DC load with

peaks at 2.5A 20% of the time, a Δ40°C temperature rise current must be greater than 1.7A:

The bq2416xx provides internal loop compensation. Using this scheme, the bq2416xx is stable with 10µF to

200µF of local capacitance on the SYS output. The capacitance on the SYS rail can be higher if distributed

amongst the rail. To reduce the output voltage ripple, a ceramic capacitor with the capacitance between 10µF

and 47µF is recommended for local bypass to SYS. A 47µF bypass capacitor is recommended for optimal

transient response.
