OUTPUT FILTER DESIGN (INDUCTOR AND OUTPUT CAPACITOR)
The TPS6223X is optimized to operate with effective inductance values in the range of 0.7
μH to 4.3μH and with
effective output capacitance in the range of 2.0
μF to 15μF. The internal compensation is optimized to operate
with an output filter of L = 1.0
μH/2.2μH and COUT = 4.7μF. Larger or smaller inductor/capacitor values can be
used to optimize the performance of the device for specific operation conditions. For more details, see the
CHECKING LOOP STABILITY section.
INDUCTOR SELECTION
The inductor value affects its peak-to-peak ripple current, the PWM-to-PFM transition point, the output voltage
ripple and the efficiency. The selected inductor has to be rated for its dc resistance and saturation current. The
inductor ripple current (
ΔIL) decreases with higher inductance and increases with higher VI N or VO UT. Equation 4
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 5. This is recommended
because during heavy load transient the inductor current will rise above the calculated value.
