| For assistance or to order, call (800) 531-5782 PT7602 Series 3.3V INPUT 10A PROGRAMMABLE INTEGRATED SWITCHING REGULATOR Revised 11/10/98 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(R) II Processor. A differential remote sense is also provided which automatically compensates for any voltage drop from the ISR to the load.

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.
