3 LM5168FEVM Evaluation Module
The LM5168FEVM is configured to deliver a regulated 10-V output, 0.25 A at 750-kHz switching frequency, and
an additional 10-V floating output. The LM5168 uses a COT control architecture, with input voltage feedforward
to provide a constant frequency regulator with tightly regulated output voltage. This type of control requires
adequate voltage ripple at the FB input to achieve stable regulation. The LM5168FEVM is set up with type III
ripple injection to minimize the output voltage ripple while ensuring a stable regulator. The LM5168FEVM also
provides the option to use type I or type II ripple injection. See the

Converter w/ Fly-Buck Converter Capability Data Sheet

3.1 Quick Start Procedure
1. Connect the input voltage supply to the VIN connector (+ and –).
2. Connect the load or loads to the VOUT and the VOUT2 connectors (+ and –).
3. Set the input supply voltage to an appropriate level between 20 V to 115 V.
4. Turn on the power supply. The EVM powers up and provides V
OUT
= 10 V, and V
OUT2
= 10 V.
See
for the location of the connectors.
CAUTION
Caution Hot surface.
Contact may cause burns.
Do not touch.
