TINY DC-DC Power Module – Input 8-28V DC – Output 5V DC 1A

This tiny power module is an easy-to-use integrated power solution that combines a 3A DC/DC converter chip with inbuilt power MOSFETs, an inductor, and passives into a 3-pin, through-hole package. The standard TO-220 pin-out allows a much-improved replacement of linear regulators packaged in this industry-standard footprint. The circuit provides much higher efficiency and output current without the need for a heatsink. This is an easy replacement of the LM7805 linear regulator with higher input voltage and output current than LM7805. Operating supply 8-28V DC, output 5V DC at 1A. The project is built using the TPS54302 chip from Texas instruments.
