Evaluates: MAX77542 in WLP Package
General Description
The MAX77542 evaluation kit (EV kit) is a fully assembled
and tested printed circuit board (PCB) that demonstrates
the MAX77542 four-phase configurable step-down regu-
lator. The board is equipped with test points and jumpers
for testing all pins on the device. Six potentiometers allow
for adjusting the SEL1/2/3/4 and CFG1/2 configuration
pins at will. There are also probe sockets on critical nodes
(VOUTx, LXx) for precise measurements. The board also
comes with some spare inductors (L5–L12) for testing out
efficiency/performance tradeoffs. The PCB is designed
with Analog Devices, Inc.'s, recommended layout of the
IC and external components. The IC sets default output
voltages by way of R15, R17, R19, and R21 but can be
changed with the potentiometers or through I
nication. Analog Devices' GUI can be used by connecting
a Windows®-based PC to J1 through a USB Type-A to
Micro-USB cable.
