Description
The PT7715 Excalibur power module
is a 20-A integrated switching regulator
(ISR) housed a 27-pin space-saving copper
package. Operating from a 5V-input bus,
the PT7715 produces a tightly regulated
supply voltage that is programmable over
the range, 1.075V to 1.85V. The output
voltage is selected via a 5-bit code. The
code adjusts the output voltage in steps of
25mV and is compatible with the Intel
VRM 9.0 specification.
This regulator is ideally suited for
applications that employ microprocessor
and DSP products that require core supply
voltages as low as 1.075V.
The PT7715 incorporates output
short-circuit protection, and a differen-
tial remote sense.
