(5)
300 F of input capacitance is required for proper operation. 300 F of ceramic or 330 F of electrolytic input capacitance can be used.
Electrolytic capacitance 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.
(6)
300 F of ceramic output capacitance is required for basic operation. The minimum output capacitance requirement increases when
TurboTrans (TT) technology is utilized. Additionally, low ESR capacitors are required for proper operation. See related Application
Information for more guidance.
(7)
This is the calculated maximum disregarding TurboTrans technology.
