The LM5161PWPFBKEVM evaluation board provides a fully functional Fly-buck regulator, employing the constant on-time (COT) operating principle. This evaluation board provides a 12-V secondary isolated output voltage over an input range of 36V to 72 V. The circuit delivers secondary output load current to 800mA. The application schematic is setup up to operate from a 48 V nominal bus. The nominal switching frequency is approximately 300 kHz. The high side and low side MOSFETs are integrated inside the LM5161.
