18 AMP “BIG-HAMMER” PROGRAMMABLE

INTEGRATED SWITCHING REGULATOR

The PT7704 is an 18 Amp high-

The output voltage of the PT7704

performance, Integrated Switching

Regulator (ISR) housed in a 27-pin

SIP package. The 18A capability

allows easy integration of the latest

high-speed, low-voltage µPs and bus

drivers into existing 5V systems.

The PT7704 series has been de-

signed to work in parallel with one or

more of the PT7749 - 18A current

boosters for increased I_outin incre-

ments of 18A.

programmable from 2.9V to 3.65V

via 4 control inputs. These inputs

are selectively grounded by the user

to set the desired output voltage.

A differential remote sense is also

provided, which can automatically

compensate for voltage drop between

the ISR to the load.

1200µF of output capacitance are

required for proper operation.

Notes: (1) ISR-will operate down to no load with reduced specifications. Please note that this product is not short-circuit protected.

(2) The PT7704 series can be easily paralleled with one or more of the PT7749 Current Boosters to provide increased output current in increments of 18A.

(3) The minimum input voltage is 4.5V or V +1.2V, whichever is greater.

out

(4) See SOA curves.

Output Capacitors: The PT7704 series requires a minimum ouput capacitance of 1200µF for proper operation. Do not use Oscon type capacitors. The maximum

allowable output capacitance is 15,000µF. See Capacitor Application Note.

Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 15ADC with a typical value of 1µH. The input capacitance must

be rated for a minimum of 1.3Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
