Figure 1 highlights the user interface items associated with the EVM. The VIN Power terminal block (J1) is
used for connection to the host input supply and the VOUT Power terminal block (J4) is used for
connection to the load. These terminal blocks accept up to 16-AWG wire.
• Use the VIN S+ and VIN S- test points along with the VOUT S+ and VOUT S- test points located near
the power terminal blocks as voltage monitoring points where voltmeters can be connected to measure
VIN and VOUT. Do not use these S+ and S- monitoring test points as the input supply or output
load connection points. The PCB traces connecting to these test points are not designed to support
high currents.
• Use the VIN scope (J2) and VOUT scope (J3) test points to monitor VIN and VOUT waveforms with an
oscilloscope. These test points are intended to use un-hooded scope probes outfitted with a low-
inductance ground lead (ground spring) mounted to the scope probe barrel. The two sockets of each
test point are on 0.1 inch centers. Connect the scope probe tip to the top socket labeled "+" and
connect the scope ground lead to the bottom socket.
• The control test points located near the bottom of the EVM test the features of the device. Refer to the
Test Points Descriptions
points.
• The VOUT SELECT jumper (J6) is provided to select the desired output voltage: 1.2 V, 1.8 V, 2.5 V,
3.3 V, 5.0 V. Before applying power to the EVM, make sure that the jumper is present and properly
positioned for the intended output voltage. Always remove input power before changing the jumper
settings.
• The device can be turned on or off using the Enable jumper (J5). Place the jumper in the ON position
to enable the device. Place the jumper in the OFF position to disable the device. The undervoltage
lockout (UVLO) can be set by populating resistors R1 and R2 located on the bottom side of the EVM.

values. The power good (PGOOD) test point is available to monitor when a valid output voltage is
present on the EVM. Additionally, the PG_PU pin is present as a convenient point to connect a pullup
voltage for the PGOOD signal.
