External Capacitors: When used with a PT7779, the PT7741 requires a minimum ouput capacitance of 330F. The maximum allowable output capacitance is
30,000F. The PT7741 also requires a minimum input capacitance of 2400F, which must be rated for a minimum of 2.0Arms of ripple current. For transient
or dynamic load applications, additional capacitance may be required. For further information, see the accompanying application note on capacitor selection for this
product.
Input Filter: An input filter inductor is optional for most applications. The input inductor must be sized to handle 32ADC with a typical value of 1H.

Description
The PT7741 is a high-output 32
Amp “Current Booster” designed to
operate with the PT7775 and
PT7779 regulators. Up to two
PT7741 boosters will operate in
parallel with one regulator, boosting
output current in increments of 32A.
Combinations of one regulator and
PT7741 current boosters can supply
enough power for virtually any mul-
tiple mega-processor application.
The booster adds a parallel output
stage that is driven directly by the
regulator. Both operate in perfect
sychronization for a low noise solution.
The PT7741 only operates with
the PT7775 and PT7775 regulators.
It is not a stand-alone product. Please
refer to the appropriate data sheet for
the performance specifications. The
current booster has the same package
options as the companion regulators.
