Overview

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.

Features
  • High power density: 50mm x 43mm, 6-layer PCB with 2oz copper
  • Wide input voltage range of 5.5V to 42V
  • High efficiency, synchronous buck-boost conversion
  • Switching frequency of 400 kHz (adjustable) with optional external synchronization (SYNC)
  • Low EMI signature with optional frequency dithering
