GENERAL DESCRIPTION
The ADP5140-EVALZ provides a complete and compact solution
that allows users to evaluate the performance of the
with
a near ideal printed circuit board (PCB) layout.
The main device on the ADP5140-EVALZ, the ADP5140,
integrates four high performance, synchronous step-down buck
regulators (Buck1 to Buck4), one boost regulator, and seven
low noise low dropout (LDO) regulators (LDO1 to LDO7).
Each voltage rail is monitored internally and any fault event is
reported to the system through the RESET pin, FAULT pin,
and STATUS pin.
The ADP5140-EVALZ has enable and sequence controls for all
regulators that allow every voltage rail to start up with a fixed
sequence.
The ADP5140-EVALZ has a serial peripheral interface (SPI) for
system control and diagnostics. A dedicated graphical user
interface (GUI) software is associated with the ADP5140-EVALZ
for flexible evaluation of the ADP5140.
For full details on the ADP5140, see the ADP5140 data sheet,
which must be consulted in conjunction with this user guide
when using the ADP5140-EVALZ.
