概述
The LMR12020 evaluation module is designed to provide the power supply design engineer with a fully functional regulatordesign which can be synchronized to an external clock between 1000 kHz and 2350 kHz. The evaluation module provides twooutput voltage options viz. 3.3V and 5V with a 2A current capability. Without an external synchronization signal, the designoperates at 2000 kHz reducing the solution size and keeping switching noise out of the AM radio band. The PCB consists of 4layers of copper on FR4 material. The first middle layer is a solid ground layer which helps in minimizing the AC current loop.The LMR12020 is thermally tied to the other layers by thermal vias directly underneath the device. This user's guide containsthe evaluation module schematic, a quick setup procedure, and a Bill-of-Materials (BOM). Refer to the LMR12020 datasheetfor complete circuit design information.
