PT7743—5.0V
Features
Description
The PT7743 is a 20 Amp “Current
Booster” for the PT7709 housed in the
same 27-pin SIP package.
Multiple PT7743 boosters will
operate in parallel with one PT7709
product, boosting output current in
increments of 20A. Combinations of a
PT7709 regulator and PT7743 current
boosters can supply power for virtually
any multiple mega-processor applica-
tion.
A PT7743 current booster adds a
parallel output stage that is driven di-
rectly by the regulator. This allows
the system to run in perfect synchron-
ization to provide a low noise solution.
The PT7743 only operates in com-
bination with a PT7709 series regulator,
and is not a stand-alone product. Please
refer to the PT7709 data sheet for the
performance specifications.
The booster uses the same 27-pin
case and has the same package options
as its companion regulator.

External Capacitors: The PT7743 requires a minimum ouput capacitance of 330F for proper operation. The PT7743 also requires an input capacitance of
1500F, which must be rated for a minimum of 1.4Arms of ripple current. For transient or dynamic load applications additional capacitance may be required.
For further information refer to the application note regarding capacitor selection for the this product.
Input Filter: An input filter inductor is optional for most applications. The inductor must be sized to handle 20ADC with a typical value of 1H.
