LM2596 DC-DC Step-Down (Buck) Adjustable Voltage Regulator Module

LM2596 DC-DC Step-Down (Buck) Adjustable Power Converter Module

The LM2596 step-down switching regulator converts high input voltages (4V-35V) down to lower, regulated DC voltages (1.23V-30V) with up to 92% power conversion efficiency. Featuring a high-precision multi-turn potentiometer for micro-volt output tuning, it stays cool where linear 7805 regulators burn up.
