(6)

300 µF 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. When the TurboTrans™ feature is utilized, the minimum output

capacitance must be increased.
