13 AMP PROGRAMMABLE

INTEGRATED SWITCHING REGULATOR

Revised 9/13/99

The PT6700 is a new series of

with Intel’s Pentium^II Processor.

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

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.

* ISR-will operate down to no load with reduced specifications.

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.
