PT7740—3.3V

32 Amp “Current Booster” for

PT7778 Regulator

SLTS117

(Revised 8/31/2000)

Description

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.

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.

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

30,000µF. The PT7740 also requires a minimum input capacitance of 2400µF, 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 1µH.
