For assistance or to order, call (800) 531-5782 PT6700 Series Revised 9/13/99 13 AMP PROGRAMMABLE INTEGRATED SWITCHING REGULATOR ackage Saving P e c a p S New The PT6700 is a new series of high-performance, 13 Amp Integrated Switching Regulators (ISRs) housed in a unique, space-saving 23-pin SIP package. The 13A capability allows easy integration of the latest highspeed, low-voltage µPs and bus drivers into existing 5V systems. The output voltage of the PT6700 can be programmed easily from 1.3V to 3.5V with a 5-bit input compatible Patent pending on package assembly Pin-Out Information Standard Application OVP DRV PROGRAMMING PINS VID0 VID1 VID2 VID3 VID4 VIN REMOTE SENSE (+) 7 6 5 4 3 L1 10 - 12 1µH R1 CIN + 1 23 PT6700 2 14 - 18 8 VOUT 19 - 22 13 COUT + LOAD PWR GOOD GND GND STBY* Specifications with Intel’s Pentium II Processor. The PT6700 includes a differential remote sense which automatically compensates for any voltage drop from the ISR to the load. Also provided are internal short circuit protection, OVP drive and a power good output signal. When over-voltage is detected, the PT6700 provides drive for an external crowbar or other protection circuitry.

Output Capacitors: The PT6700 series requires a minimum ouput capacitance of 330µF. The maximum allowable output capacitance is 15,000µF. Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 12.5ADC with a typical value of 1µH. The input capacitance must be rated for a minimum of 1.6Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
