Pin Function

The PT7713 Excalibur™ power module

is a 20-A integrated switching regulator

(ISR) housed a 27-pin space-saving copper

package. Operating from a 3.3V input

bus, the PT7713 produces a tightly regu-

lated supply voltage that is programmable

over the range, 1.8V to 2.55V. The

output voltage is selected via a unique

4-bit input code that adjusts the output

in steps of 50mV.

This regulator is most suitable for

microprocessor and DSP applications

requiring core or I/O logic supply voltages

as low as 1.8V.

The PT7713 incorporates output short-

circuit protection, and a differential remote

sense to compensate for voltage drop

between the regulator and load.
