8.2.2.1.1 Selecting the Inductor

Placement of an inductor is required between the external FETs and the output capacitors. Together, the inductor and output capacitors make the double-pole that contributes to stability. In addition, the inductor is directly responsible for the output ripple, efficiency, and transient performance. As the inductance used increases, the ripple current decreases, which typically results in an increased efficiency. However, with an increase in inductance used, the transient performance decreases. Finally, the inductor selected must be rated for appropriate saturation current, core losses, and DC resistance (DCR).

Equation 5 shows the calculation for the recommended inductance for the controller.

Equation 5. TPS650864

where

  • VOUT is the typical output voltage
  • VIN is the typical input voltage
  • fSW is the typical switching frequency when loaded, 1 MHz unless otherwise noted
  • IOUT(MAX) is the maximum load current
  • KIND is the ratio of ILripple to the IOUT(MAX). For this application, TI recommends that KIND is set to a value from 0.2 to 0.4. Higher values have improved transient performance, lower values have improved efficiency

With the chosen inductance value, the peak current for the inductor in steady state operation, IL(max), can be calculated using Equation 6. The rated saturation current of the inductor must be higher than the IL(max) current.

Equation 6. TPS650864
