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 high- speed, 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 with Intel’s Pentium  II Processor. The PT6700 includes a differential remote sense which automatically com- pensates 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 de- tected, the PT6700 provides drive for an external crowbar or other protec- tion 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.
