Application Notes
Increasing the Output of the PT7710 Family of
ISRs with a 20-A Compatible Current Booster
The output of PT7710 family of regulators (PT7711–
PT7716) can produce an additional 20-A output using a
compatible current booster module. Two booster modules
are available. They are the PT7744 and PT7745, which
are compatible with regulators that operate off 3.3-V
or 5-V input buses respectively. Refer to Table 2-1 for
regulator/booster compatiblity.
The booster modules are controlled directly by the regu-
lator and effectively add a parallel output stage. They
operate sychronously, to provide a low-noise solution.
Up to two booster modules can be connected to a PT771x
regulator. Each booster added increases the regulator’s
output current by 20A, for up to 60A of output current.
Current boosters are not stand-alone products, and can
only operate with a regulator. They are housed in the same
package as the regulator, and share the same mechanical
outline. Except for an increase in output current, the
overall performance of a regulator/booster combination
is identical to that of a stand-alone regulator. For more
details refer to the applicable regulator specifications.

Notes:
1. Each booster requires the same amount of input and
output capacitance as recommended for a stand-alone
regulator. Consult the individual data sheet of the
applicable regulator, and the related application note
regarding capacitor selection for this product family.
2. The 1-μH filter choke located at the input of each
regulator and booster module (L
in
) is optional for most
applications. If specified, each inductor must be sized
to handle 20ADC at full output load.
3. The pin-out of the current booster modules include a
number pins identified, “No Connect” (see Table 2-2).
These pins are not connected internally to the module
but must be soldered to a pad to preserve the unit’s
mechanical integrity.
4. A similar PCB footprint and trace layout between the
regulator and each booster will facilitate current sharing
between all modules.
