Power supply unit LM2596 DC-DC step-down

Features: thick circuit boards, advanced solid-state capacitor, overcurrent protection, and increased temperature protection. Instructions: 1. Power (3-40 volts), power indicator light, the unit operates correctly. 2. Adjust the blue voltage meter knob (generally clockwise for boost, counterclockwise then flip down) and use a multimeter to monitor the desired output voltage. Note: Input voltage range: DC 3.2V to 40V (input voltage must be higher than output voltage by more than 1.5V. Boost cannot be used.) Output voltage range: DC voltage from 1.25V to 35V continuously adjustable, high efficiency (92%) at maximum output current 3A. Measured input voltage at 12V, output current at 5V is load regulation less than 1%. Model: LM2596 Input voltage: DC 3V – 40V Output voltage: DC 1.5V – 35V (adjustable) Output current: 3A (maximum) Conversion efficiency: 92% (maximum) Switching frequency: 65 kHz Correction: asynchronous correction Unit feature: non-isolated buck converter Operating temperature: -45°C to +85°C Load regulation: ± 0.5% Voltage regulation: ± 2.5%
