The PT7706 is a high-performance
18-Amp Integrated Switching Regulator
(ISR), housed in a 27-pin SIP package.
The 18A capability allows easy integra-
tion of the latest high-speed, low-voltage
Ps, DSPs, ASICs, and bus drivers into
existing 3.3V systems.
The PT7706 series has been designed
to work in parallel with one or more of
the PT7749 - 18A current boosters for
increased I
out in increments of 18A.
The output voltage of the PT7706 can
be easily programmed with a 4 bit input
compatible with Intel’s Pentium II Pro-
cessor. A differential remote sense is also
provided which automatically compen-
sates for any voltage drop from the ISR to
the load.
An input capacitance of 1200F, and
output capacitance of 330F are required
for proper operation.
Cin = Required 1200F electrolytic
Cout= Required 330F electrolytic
L1 = Optional 1H input choke

Notes: (1) The ISR will operate down to no load with reduced specifications. Please note that this product is not short-circuit protected.
(2) The PT7706 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 3.1V or Vout+1.2V, whichever is greater.
(4) See Safe Operating Area curves.
Output Capacitors: The PT7706 series requires a minimum ouput capacitance of 330F for proper operation. Do not use Oscon type capacitors. The maximum
allowable output capacitance is 15,000F.
Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 18ADC with a typical value of 1H. 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.
