RTT Resistor Selection
The TurboTrans resistor value, RTT can be determined from the TurboTrans programming equation:
Where CO is the total output capacitance in F. CO values greater than or equal to 1500 F require RTT to be
a short, 0
.
To ensure stability, a minimum amount of output capacitance is required for a given RTT resistor value. The
value of RTT must be calculated using the minimum required output capacitance determined from the
capacitor transient response charts above.
