9.1.1.2.7 Non-TurboTrans Output Capacitance

If the TurboTrans feature is not used, minimum ESR and maximum capacitor limits must be followed. System stability may be effected and increased output capacitance may be required without TurboTrans.

When using the PTH08T250W, observe the minimum ESR of the entire output capacitor bank. The minimum ESR limit of the output capacitor bank is 7 mΩ. A list of preferred low-ESR type capacitors, are identified in Table 4.

When using the PTH08T250W without the TurboTrans feature, the maximum amount of capacitance is 1000 μF of ceramic type. Large amounts of capacitance may reduce system stability.

Utilizing the TurboTrans feature improves system stability, improves transient response, and reduces the amount of output capacitance required to meet system transient design requirements.
