说明
- LM27342MYEVAL, Demonstration Board is designed to provide the power supply design engineer with a fully functional regulator design which can be synchronized to an external clock between 1000 kHz and 2350 kHz. The evaluation board provides a 3.3V output with a 2A current capability. The wide input voltage ranges from 5V to 20V. Without an external synchronization signal, the design operates at 2000 kHz reducing the solution size and keeping switching noise out of the AM radio band. The printed circuit board consists of 4 layers of copper on FR4 material
