10pcs DC-DC Buck Converter Step Down Module LM2596S Power Supply Output 1.25V-35V 3A adjustable Dense vias, heat and strong! Increase in the input and output terminals respectively X7R high-Q high frequency bypass capacitor, electromagnetic compatibility super! Input voltage range: DC 3.2V to 35V (input voltage must be higher than the voltage output to 1.5V or more can not be boosted.) Output Voltage Range: 1.25V to 30V DC voltage is continuously adjustable, high efficiency (maximum 92%) of the maximum output current of 3A. Found 12V input, load regulation 5V 1A output current is lower than 1% Note: The input and output can not be reversed, reverse might burn chips; This is a step-down module, the input voltage is higher than the required output voltage; Output 2A or less long period of time without additional heat sink output current is greater than 2.5A (or output power greater than 10W) to work long hours please add heat sink. Electrical parameters: Input: DC 3.2V to 35V (input voltage must be more than the output voltage can not be higher than boost 1.25v.) Output: 1.25V to 30V DC voltage is continuously adjustable, high efficiency and maximum output current of 3A. Features: All solid capacitors using SANYO, 36u thick circuit boards, high-Q inductors with high power output LED indicator Size: 41 (L) * 20 (W) * 14 (H) mm (including potentiometers) Taobao minimum with locating hole with LED indicator DC-DC
