Output Filter And Loop Stability

The devices of the TPS6213xA-Q1 family are internally compensated to be stable with L-C filter combinations corresponding to a corner frequency to be calculated with Equation 12:

Proven nominal values for inductance and ceramic capacitance are given in Table 3 and are recommended for use. Different values may work, but care has to be taken on the loop stability which is affected. More information including a detailed LC stability matrix can be found in SLVA463.

The TPS6213xA-Q1 includes an internal 25pF feedforward capacitor, connected between the VOS and FB pins. This capacitor impacts the frequency behavior and sets a pole and zero in the control loop with the resistors of the feedback divider, per equation Equation 13 and Equation 14:

Though the TPS6213xA-Q1 is stable without the pole and zero being in a particular location, adjusting their location to the specific needs of the application can provide better performance in Power Save mode and/or improved transient response. An external feedforward capacitor can also be added. A more detailed discussion on the optimization for stability vs. transient response can be found in SLVA289 and SLVA466.
