Description
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.
