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.
