GENERAL DESCRIPTION
The XRP7724/7725EVB-DEMO-2 board is a
complete four channel power system. It is
configured to provide 3.3V, 2.5V 1.5V and 1V
at a maximum of 3A, 3A, 5A and 10A loads
respectively. The 1.5V and 1V supplies can be
adjusted in 2.5mV increments, the 2.5V
supply in 5mV increments, and the 3.3V
supply is adjustable in 10mV increments. The
order and ramp rates for each supply can be
programmed to accommodate any sequencing
requirement. All power supply operations can
be controlled over an I
2
C interface. Faults,
output voltages and currents can also be
monitored. Two GPIO and three PSIO signals
are available and can be programmed to
provide a variety of functions. Unused
GPIO/PSIO pins can be programmed as I/O
expansion for a microcontroller. The board is
supported by PowerArchitect
TM
5.1 or later and
plugs directly onto the interposer board acting
as an interface to an Arduino controller or
Exar’s XCM.
