Application Notes
Table 2-1: Input/Output Capacitors
Capacitor Recommendations for
the
PT6460 & PT6470 Regulator Series
Input Capacitor:
The recommended input capacitor is determined by a
minimum of 470 F capacitance and 700 mA minimum
ripple current rating.
Ripple current and <100 m
equivalent series resistance
(ESR) values are the major considerations, along with
temperature, when when designing with different types
of capacitors. Tantalum capacitors have a recommended
minimum voltage rating of 2
× (maximum DC voltage +
AC ripple). This is necessary to insure reliability for
input voltage bus applications.
Output Capacitors (Optional):
The ESR of the capacitors should be less than 150 m
.
Electrolytic capacitors have marginal ripple performance at
frequencies greater than 400 kHz but excellent low fre-
quency transient response. Above the ripple frequency,
ceramic capacitors are necessary to improve the transient
response and reduce any high frequency noise components
apparent during higher current excursions. Preferred low
ESR type capacitor part numbers are identified in Table 2-1.
PT6460 & PT6470 Series
Tantalum Capacitors( Optional Output Capacitors)
Tantalum type capacitors can be used for the output but
only the AVX TPS, Sprague 593D/594/595, or Kemet
T495/T510 series. These capacitors are recommended
over many other tantalum types due to their higher rated
surge, power dissipation, and ripple current capability.
As a caution the TAJ series by AVX is not recommended.
This series has considerably higher ESR, reduced power
dissipation, and lower ripple current capability. The TAJ
series is less reliable than the AVX TPS series when deter-
mining power dissipation capability. Tantalum or Oscon
types are recommended for applications where ambient
temperatures fall below 0 °C.
Capacitor Table
Table 2-1 identifies the characteristics of capacitors from
a number of vendors with acceptable ESR and ripple
current (rms) ratings. The number of capacitors required
at both the input and output buses is identified for each
capacitor type.
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 100kHz) are critical parameters necessary to insure both
optimum regulator performance and long capacitor life.
