A 330 F input capacitor is required for proper operation. The capacitor must be rated for a minimum of 400 mA rms of ripple current.
An additional 22-
F ceramic input capacitor is recommended to reduce rms ripple current.
(8)
100 F ceramic and 150 F non-ceramic external output capacitance is required for basic operation. The minimum output capacitance
requirement increases when TurboTrans (TT) technology is used. See the Application Information for more guidance.
(9)
This is the calculated maximum disregarding TurboTrans technology. When the TurboTrans feature is used, the minimum output
capacitance must be increased. See the TurboTrans application notes for further guidance.
(10) When using TurboTrans technology, a minimum value of output capacitance is required for proper operation. Additionally, low ESR
capacitors are required for proper operation. See the TurboTrans application notes for further guidance.
(11) This is the calaculated maximum when using the TurboTrans feature. Additionally, low ESR capacitors are required for proper operation.
See the TurboTrans application notes for further guidance.
