Output Capacitor Selection
The advanced fast-response voltage mode control scheme of the TPS6226x allows the use of tiny ceramic
capacitors. Ceramic capacitors with low ESR values have the lowest output voltage ripple and are
recommended. The output capacitor requires either an X7R or X5R dielectric. Y5V and Z5U dielectric capacitors,
aside from their wide variation in capacitance over temperature, become resistive at high frequencies.
At nominal load current, the device operates in PWM mode and the RMS ripple current is calculated as:
(3)
At nominal load current, the device operates in PWM mode and the overall output voltage ripple is the sum of the
voltage spike caused by the output capacitor ESR plus the voltage ripple caused by charging and discharging the
output capacitor:
(4)
At light load currents, the converter operates in Power Save Mode and the output voltage ripple is dependent on
the output capacitor and inductor value. Larger output capacitor and inductor values minimize the voltage ripple
in PFM mode and tighten DC output accuracy in PFM mode.
Input Capacitor Selection
An input capacitor is required for best input voltage filtering, and minimizing the interference with other circuits
caused by high input voltage spikes. For most applications, a 4.7mF to 10mF ceramic capacitor is recommended.
Because ceramic capacitor loses up to 80% of its initial capacitance at 5 V, it is recommended that 10mF input
capacitors be used for input voltages > 4.5V. The input capacitor can be increased without any limit for better
input voltage filtering. Take care when using only small ceramic input capacitors. When a ceramic capacitor is
used at the input and the power is being supplied through long wires, such as from a wall adapter, a load step at
the output or VIN step on the input can induce ringing at the VIN pin. This ringing can couple to the output and
be mistaken as loop instability or could even damage the part by exceeding the maximum ratings.
