Description for the LM5175RHFEVM-HD
The LM5175RHFEVM-HD demonstrates a compact buck-boost design using the LM5175 high performance 4-switch buck-boost controller. This evaluation module is designed to operate from input voltage range of 5.5 V-42 V and provide a regulated 12 V output with load current up to 6 A. The high efficiency transition region control method of the LM5175 produces high efficiency. The switching frequency is set at 400kHz and can be synchronized to an external clock signal.
