300 F of ceramic or 330 F of electrolytic input capacitance is required for proper operation. Electrolytic capacitance must be rated for
a minimum of 450 mA rms of ripple current. An additional 22-mF ceramic input capacitor is recommended to reduce rms ripple current.
(8)
200 F ceramic external output capacitance is required for basic operation. The required ceramic output capacitance can be made up of
2 × 100 F or 4 × 47 F. The minimum output capacitance requirement increases when TurboTrans (TT) technology is used. See the
Application Information for more guidance.
(9)
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.
(10) 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.
