Description
The PT7716 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 PT7716 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 VRM 9.0 compatible.
This regulator is ideally suited for
applications that employ microprocessor
and DSP products that require core supply
voltages as low as 1.075V.
The PT7716 includes a Shutdown
control, Differential Remote Sense, and
Short-Circuit Protection.
