Detailed Descriptions
This section describes the connectors and the test points on the EVM and how to properly connect, set up
and use the LM5164-Q1 EVM. See
for a top view of the EVM.
VOUT —
Output voltage of the converter.
VOUT connector and test point connected to the power inductor and the output capacitors. Connect
the loading device between VOUT and GND connectors to provide loading to the regulator.
Connect the loading device to the board with short wires to handle the DC output current.
GND —
Ground of the converter.
It is connected to the LM5164-Q1 GND as well as the return terminals of the input and output
capacitors. GND is the current return path for both supply voltage and load. Connect to supply and
load grounds with short wires.
VIN —
Input voltage to the converter.
VIN connector and test point connects to the input capacitors and the VIN pin of the LM5164-Q1.
Connect the supply voltage from a power supply or a battery between the VIN and GND
connectors. The voltage range should be higher than 6 V for the device to be active. V
VIN
higher
than 15 V provides a regulated 12 V output voltage. To avoid damaging the device V
VIN
should be
no greater than 100 V. The current limit on the supply should be high enough to provide the needed
supply current when the output is fully loaded. The supply voltage should be connected to the
board with short wires. If long cables are used to power up the board, add a damping capacitor C
8
to avoid oscillation between the cable parasitic inductance and the low-ESR input ceramic
capacitors.
VIN-EMI —
Input voltage to input filter of the converter.
If an input filter is desired between the supply voltage and the LM5164-Q1, connect the supply
voltage between VIN-EMI and GND-EMI. The supply voltage should be connected to the board with
short wires.
