Features
Description
The PT7740 is a high-output 32
Amp “Current Booster” designed to
operate with the PT7778 regulator.
Up to two PT7740 boosters will
operate in parallel with a PT7778,
boosting output current in increments
of 32A. Combinations of a PT7778
series regulator and PT7740 current
boosters can supply enough power for
virtually any multiple 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 PT7740 only operates with a
PT7778 regulator and is not a stand-
alone product. Please refer to the
PT7778 data sheet for the perfor-
mance specifications. The current
booster has the same package options
as its companion regulator.

External Capacitors: When used with a PT7778, the PT7740 requires a minimum ouput capacitance of 330F. The maximum allowable output capacitance is
30,000F. The PT7740 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.
