LM5175/5176-synchronous boost-buck

Overview

Running diagram:

Measured efficiency

Output ripple @12v 2.4A

Debugging method:

Please use a 0 ohm resistor for the gate resistor first.

Then short the jumper cap to CCM. If the input voltage is greater than the output voltage, adjust the gate drive resistor to eliminate the ringing of SW.

DCM can improve efficiency in light load mode
