3 LM5168PEVM Evaluation Module

The LM5168PEVM is configured to deliver a regulated 12-V output, 0.3 A at 500-kHz switching frequency. The LM5168 uses a COT control architecture, with input voltage feed-forward 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 LM5168PEVM is set up with type III ripple injection to minimize the output voltage ripple while ensuring a stable regulator. The LM5168PEVM also provides the option to use type I or type II ripple injection. See the LM516x-Q1 0.65/0.3-A, 120-V Step-Down Converter w/ Fly-Buck Converter Capability Data Sheet for more information. Figure 3-1 and Figure 4-1 show an overall view of the LM516PEVM and the schematic, respectively.
