LM2596 IC : PinOut, Features, Specifications, Circuit, Working, Datasheet & Its Applications

July 15, 2025 By WatElectronics

LM2596 IC

A step-down (buck converter) is a DC-to-DC converter that reduces voltage when current is increased from its input supply to its load. These converters provide much better power efficiency than linear regulators. Its efficiency is frequently over 90%, which makes it very useful for different tasks like changing the main supply voltage of a computer. So, step-down converters normally have a minimum of two semiconductors like a transistor and a diode, while current buck converters often change the … [Read more...]
