C capacitor chart. Dividing 80mV by 20A gives 4mV/A
transient voltage deviation per amp of transient load setp.
Select 4mV/A on the Y-axis and read across to the “With
TurboTrans” plot. Following this point down to the X-axis gives
us a minimum required output capacitance of approximately
1700F. The required RTT resistor value for 1700F can then
be calculated or selected from the below table. The required
RTT resistor is approximately 31.6K.
To see the benefit of Turbo Trans
TM, follow the 4mV/A marking
across to the “Without TurboTrans” plot. Following that point
down shows that you would need a minimum of 5500F of
output capacitance to meet the same transient deviation limit.
This is the benefit of Turbo Trans
TM .
A typical Turbo Trans
TM application schematic is also shown.
RTT Resistor Selection
The Turbo Trans
TM resistor value, RTT can be determined from
the Turbo Trans
TM programming equation, see the equation
below.

Where Co is the total output capacitance in F. Co values
greater than or equal to 4700 F require RTT to be a short,
