DC-DC LM2596 1.8A Mini Step Down Module

The Mini360-HM is an ultra-compact DC-DC step-down converter designed for space-constrained electronics, robotics, and embedded projects. At its core sits the MP2307 monolithic synchronous buck regulator, which integrates 100mΩ MOSFETs to deliver up to 3A of peak output current (1.8A rated continuous) across an input range of 4.75V to 23V. The output voltage is adjustable from 1.0V to 17V via an onboard potentiometer, always remaining below the input level for proper buck operation. A fixed 340kHz switching frequency enables a compact footprint while maintaining high conversion efficiency—up to 95% according to the MP2307 datasheet—and output ripple is held to just 30mV under no-load conditions. The module features non-isolated synchronous rectification for improved thermal performance, along with load regulation of ±0.5% and voltage regulation of ±2.5%. With dimensions of only 17mm × 11mm × 3.8mm and a weight of roughly 2.3 grams, this Mini360 power supply module can be embedded into tight enclosures, RC models, portable devices, and distributed power architectures where a reliable step-down converter is needed.
