2 Setup
This section describes the test points and connectors on the EVM and how to properly connect, set up, and use
the LM76005QEVM. Refer to
for a top view of the EVM and relative placement of the different test
points and connectors.

2.1 Input/Output (I/O) Connector Description
VIN – Terminal on
J1
The power input terminal for the converter
VOUT – Terminal
on J2
The regulated output voltage for the converter
VIN_EMI – Terminal
on J6
Used to supply the input voltage through an on board LC filter (if one is needed for
conducted EMI/EMC measurement). The L1 and CBULK component pads are located on
the bottom side of the EVM. Refer to
for initial suggestion of component
values. J6 and LC filter are not populated on this EVM.
GND – Terminal on
J1, J2 and J6
The ground reference for the converter
EN – Testpoint
Used to enable the converter by supplying a voltage greater than 1.2 V (typ) or just to
monitor the voltage on this pin whenever a resistor divider is in place (for precision enable
applications). The regulator is enabled when V
IN
> 3.5 V. This threshold can be calculated
