5V 1A Buck Converter. Replacement for LM7805

The DC-DC synchronous rectification step-down module has high conversion efficiency and low heat generation.

The pins are compatible with the LM7805 three-terminal regulator block and can be directly replaced.

A perfect replacement for the LM7805 used in the ZX Spectrum which runs very hot!! This repalcement is more efficient and runs a lot cooler.
