RTT Resistor Selection
The TurboTrans resistor value, RTT can be determined from the TurboTrans programming, see Equation 4 .
Where CO is the total output capacitance in F. CO values greater than or equal to 5000 F require RTT to be a
short, 0
. (RTT results in a negative value when CO > 5000 F).
To ensure stability, the value of RTT must be calculated using the minimum required output capacitance
determined from the capacitor transient response charts above.
