15 AMP “CURRENT BOOSTER”
FOR PT7750 SERIES
PT7747
Ordering Information
PT7747t
t
The PT7747 is a new high-perfor-
mance 15 Amp “Current Booster” for
the PT7750 Series housed in a 27-pin
SIP package. Multiple PT7747 boost-
ers will operate in parallel with the
PT7750 Series boosting output current
in increments of 15A . Combinations
of PT7750s and PT7747 current
boosters can easily supply enough
power for virtually any multiple
megaprocessor application.
A PT7747 current booster adds a parallel
output stage driven by the PT7750. As such,
the system runs in perfect sychronization
providing a low noise solution.
The PT7747 only operates in combina-
tion with the PT7750 series and is not a
stand-alone product. Therefore please refer
the PT7750 series data sheet for perfor-
mance specifications. The PT7747 also has
the same mechanical dimensions and pack-
age options as the PT7750 series.
Features
Output Capacitors: The PT7750/PT7747 series requires a minimum output capacitance of 2000F for proper operation. Do not use Oscon type capacitors. The maximum
allowable output capacitance is (42,000 4 Vout)F for the PT7751, (96,000 4 Vout)F for the PT7756, or 15,000F, whichever is less.
Input Filter:
An input inductor is optional for most applications. The input inductor must be sized to handle 9ADC with a typical value of 1H. The input capacitance
must be rated for a minimum of 8.0 Arms of ripple current when operated at maximum output current and maximum output voltage. Contact an applications engi-
neer for input capacitor selection for applications at other output voltages and output currents.
