Figure 14. Ceramic Output Filter Capacitors Circuit
Output Filter Component Selection
Using Equation 11, the minimum inductor value is 12
H. A value of 15 H is chosen for this design.
When using ceramic output filer capacitors, the recommended LC resonant frequency should be no more than
7 kHz. Since the output inductor is already selected at 15
H, this limits the minimum output capacitor value to:
The minimum capacitor value is calculated to be 34
F. For this circuit a larger value of capacitor yields better
transient response. A single 100-
F output capacitor is used for C3. It is important to note that the actual
capacitance of ceramic capacitors decreases with applied voltage. In this example, the output voltage is set to
3.3 V, minimizing this effect.
External Compensation Network
When using ceramic output capacitors, additional circuitry is required to stabilize the closed loop system. For
this circuit, the external components are R3, C4, C6, and C7. To determine the value of these components, first
calculate the LC resonant frequency of the output filter:
For this example the effective resonant frequency is calculated as 4109 Hz
The network composed of R1, R2, R3, C5, C6, and C7 has two poles and two zeros that are used to tailor the
overall response of the feedback network to accommodate the use of the ceramic output capacitors. The pole
and zero locations are given by the following equations:
