Standard Application
PT6702—3.3V
The PT6702 is 13Amp fully integrated
switching regulator housed in a unique, space-
saving package. The PT6702 operates from
+3.3V input to provide a high-performance,
low-voltage power source for the industry’s
latest Ps, DSPs, and bus drivers.
The output is programmable from 1.3V to
2.05V with a 4-bit input, compatible with
Intel’s Pentium II Processor.
The PT6702 has short circuit protection,
a “Power Good” output, and an over-voltage
protection (OVP) drive output.

Notes: (1) ISR-will operate down to no load with reduced specifications.
(2) The minimum input voltage is 3.1V or Vout+1.1V, whichever is greater.
(3) For operation below 0°C, Cin and Cout must have stable characteristics. Use either low ESR tantalum or Oscon capacitors.
(4) See Safe Operating Area curves.
(5) If the remote sense ground is not used, pin 7 must be connected to pin 8 for optimal output voltage accuracy.
Output Capacitors: The PT6702 requires a minimum ouput capacitance of 330F for proper operation. The maximum allowable output capacitance is 15,000F.
Input Filter: An input filter is optional for most applications. The input inductor must be sized to handle 10.0ADC with a typical value of 1H. The input capacitance must
be rated for a minimum of 2.0Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
