Low-Cost Boost Converter 3.3V Input – 5V Output at 250mA

This is a low-cost boost converter that converts a 3.3V input to 5V at 250mA load current. The LM2578A chip is used to build this project. The LM2578A is a switching regulator which can easily be set up for such DC-to-DC voltage conversion circuits as the buck, boost and inverting configurations. In this board, the IC is configured as a boost converter. The operating frequency is 50Khz.
