TPA2014D1 CAPACITOR EQUATIONS
The value of the boost capacitor is determined by the minimum value of working capacitance required for stability
and the maximum voltage ripple allowed on VCC in the application. The minimum value of working capacitance is
10
F. Do not use any component with a working capacitance less than 10 F.
For X5R or X7R ceramic capacitors, Equation 4 shows the relationship between the boost capacitance, C, to
load current, load voltage, ripple voltage, input voltage, and switching frequency (ICC, VCC, ΔV, VDD, fboost
respectively). Insert the maximum allowed ripple voltage into Equation 4 to solve for C. A factor of 2 is included
to implement the rules and specifications listed earlier.
For aluminum or tantalum capacitors, Equation 5 shows the relationship between he boost capacitance, C, to
load current, load voltage, ripple voltage, input voltage, and switching frequency (ICC, VCC, ΔV, VDD, fboost
respectively). Insert the maximum allowed ripple voltage into Equation 5 to solve for C. Solve this equation
assuming ESR is zero.
Capacitance of aluminum and tantalum capacitors is normally not sensitive to applied voltage so there is no
factor of 2 included in Equation 5. However, the ESR in aluminum and tantalum capacitors can be significant.
Choose an aluminum or tantalum capacitor with ESR around 30 m
. For best performance using of tantalum
capacitor, use at least a 10 V rating. Note that tantalum capacitors must generally be used at voltages of half
their ratings or less.
