APPLICATION INFORMATION (continued)
Figure 44. Dynamic Voltage Scaling on Vout1 Controlled by DEF_1 pin
Figure 45. TPS62403 1.575V/2.8V Outputs
The converters are designed to operate with a minimum inductance of 1.75
µH and minimum capacitance of 6µF.
The device is optimized to operate with inductors of 2.2
µH to 4.7µH and output capacitors of 10µF to 22µF.
The selected inductor has to be rated for its DC resistance and saturation current. The DC resistance of the
inductor will influence directly the efficiency of the converter. Therefore an inductor with lowest DC resistance
should be selected for highest efficiency.
Equation 6 calculates the maximum inductor current under static load conditions. The saturation current of the
inductor should be rated higher than the maximum inductor current as calculated with Equation 7. This is
recommended because during heavy load transient the inductor current rises above the calculated value.
