Capacitor Recommendations for the PT5400
SWIFT ? Series of Power Modules
Input Capacitors
The recommended input capacitance is determined by
100 μF minimum capacitance, 300 mA (rms) minimum
ripple current rating, and less than 300 m ? equivalent
series resistance (ESR). The ripple current rating, ESR,
and operating temperature are the major considerations
when selecting the input capacitor.
It is recommended that tantalum capacitors have a mini-
mum voltage rating of at least twice the working voltage,
including the ac ripple. This is necessary to insure reli-
ability with 3.3-V input voltage bus applications.
Output Capacitors (optional)
The ESR of the output bulk (non-ceramic) capacitance
must be between 10 m ? ≤ ESR ≤ 200 m ? . Electrolytic
capacitors have poor ripple performance at frequen-
cies greater than 400 kHz but excellent low frequency
transient response. Above the ripple frequency, ceramic
decoupling capacitors are recommended to improve the
transient response and reduce any high frequency noise
Table 2-1; Recommended Input/Output Capacitors
components apparent during higher current excursions. A
maximum of 100 μF ceramic capacitance may be added to
the output bus.
Tantalum/ Ceramic Capacitors
Tantalum capacitors are acceptable on the output bus.
Tantalum, Os-con?, or ceramic capacitor types are rec-
ommended for applications where ambient temperatures
fall below 0 °C. Ceramic capacitors may be used instead
of electrolytic types on both the input and output bus.
The input bus must have at least the minimum amount of
capacitance. For the output bus the total amount of
ceramic capacitance should be limited to 100 μF.
Capacitor Tables
Table 2-1 identifies vendors with acceptable ESR and
maximum allowable ripple current (rms) ratings. Capaci-
tors recommended for the output are identified under
the Output Bus column with the required quantity.
This is not an extensive capacitor list. Capacitors from other
vendors are available with comparable specifications. Those
listed are for guidance. The RMS ripple current rating and
ESR (at 100 kHz) are critical parameters necessary to insure
both optimum regulator performance and long capacitor life.
