Series
PT7602
The PT7602 is a new series of
high-performance, 10A Integrated
Switching Regulators (ISRs) housed in
a 27-pin SIP package. The 10A
capability allows easy integration of the
latest high-speed, low-voltage Ps,
DSPs, ASICs, and bus drivers into
existing 3.3V systems.
The output voltage of the PT7602
can be easily programmed with a 4 bit
input compatible with Intel’s Pentium
II Processor. A differential remote sense
is also provided which automatically
compensates for any voltage drop from
the ISR to the load.

* ISR-will operate down to no load with reduced specifications. Please note that this product is not short-circuit protected.
** The minimum input voltage is 3.1V or Vout+1.2V, whichever is greater.
Output Capacitors: The PT7602 series requires a minimum ouput capacitance of 330F for proper operation. Do not use Oscon type capacitors. The maximum
allowable output capacitance is 7,500F.
Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 10ADC with a typical value of 1H. The input capacitance must be
rated for a minimum of 1.0Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
