LM2596 S SeriesDC-DC Voltage Adjustable Buck Converter

This high-efficiency LM2596S step-down (buck) switching regulator runs reliably under heavy loads, tailored for DIY power supplies, robotics, and custom electronics projects. Ideal for engineering students and hobbyists needing to precisely step down higher voltage battery packs or power adapters to stable 3.3V, 5V, or 12V rails. Easy three- or four-terminal setup; Drop-in replacement for bulky linear regulators or inefficient power modules needing robust, compact voltage control. Pairs well with microcontrollers and development boards for clean, regulated power. Specifications: Input Voltage: 4V - 40V Output Voltage: 1.3V - 37V Output Current: 3A (Maxamum) Conversion Efficiency: Up To 92% Output Ripple: <30mV Switching Frequency: 150KHz Working temperature: -45C to +85C Size (length x width x height): 44mm * 22mm * 16mm (1.75inch x 8.4inch x 0.62inch) Regulation: Input voltage must be a minimum of 1.5V above output voltage for regulation to occur.
