(8)

In addition to the required input electrolytic capacitance,

≥ 22

µF of ceramic capacitance is recommended to reduce the high-frequency

reflected ripple current.

(9)

Required capacitors with TurboTrans. See the TurboTrans Application information for Capacitor Selection

Capacitor Types:

a. Type B = (1,000 < capacitance × ESR

≤ 5,000)

b. Type C = (5,000 < capacitance × ESR

≤ 10,000)

(10) N/R – Not recommended. The voltage rating does not meet the minimum operating limits.

(11) Total bulk nonceramic capacitors on the output bus with ESR of

≥ 15mΩ to ≤ 30mΩ requires an additional ≥ 200

µF of ceramic

capacitance.
