Features
The PT7746 is a new high-perfor-
mance 32 Amp “Current Booster” for
the PT7770 Series housed in a 27-pin
SIP package.
Multiple PT7746 boosters will
operate in parallel with the PT7770
boosting output current in incre-
ments of 32A.
Combinations of
PT7770s and PT7746 current
boosters can easily supply enough
power for virtually any multiple
mega-processor application.
A PT7746 current booster adds a parallel
output stage driven by the PT7770. As such,
the system runs in perfect sychronization
providing a low noise solution.
The PT7746 only operates in
combination with the PT7770 series and is
not a stand-alone product. Therefore, please
refer to the PT7771, PT7772, or PT7777
series data sheet for performance
specifications. The PT7746 also has the
same mechanical dimensions and package
options as the PT7770 series.

Output Capacitors: When used with a PT7771 or PT7772, the PT7746 requires a minimum ouput capacitance of 2400F. When used with a PT7777,
the PT7746 requires a minimum ouput capacitance of 680F for proper operation. Do not use Oscon type capacitors. The maximum allowable output
capacitance is 30,000F.
Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 32ADC with a typical value of 1H. The input
capacitance must be rated for a minimum of 2.6Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
