SLUS774B – AUGUST 2007 – REVISED OCTOBER 2007
Figure 23. Small Signal Equivalent Block Diagram
The following figures plot the TPS5438x Output-to-Vc gain and phase versus frequency for various duty cycles
(10%, 30%, 50%, 70%, 90%) at three (200 mA, 400 mA, 600 mA) peak-to-peak ripple current levels. The loop
response curve selected to compensate the loop is based on the duty cycle of the application and the ripple
current in the inductor. Once the curve has been selected and the inductor value has been calculated, the output
capacitor is found by calculating the L-C resonant frequency required to compensate the feedback loop. A brief
example follows the curves.
Note that the internal error amplifier compensation is optimized for output capacitors with an ESR zero frequency
between 20 kHz and 60 kHz. See the following sections for further details.
