electrolight LM2596S Buck Converter DC-DC Adjustable 3A Step Down Power Supply Module Voltage Regulator 4V-35V to 1.23V-30V Adjustable Module. Power Supply Electronic Hobby Kit

Specifications: Conversion efficiency: 92%(highest) Switching frequency: 150KHz Output ripple: 30mA9maxmum) product description: This is the use of all-chip aluminum electrolytic capacitors, high-Q high-power inductors, the size is not the smaller the better, consider the heat, the area is more conducive to heat dissipation! Diodes SS34 use 5A components, not a large component of sesame seeds, used friends know! In the input and output, respectively, increase the X7R high Q high frequency bypass capacitor, electromagnetic compatibility super! Product use: Clockwise adjustment onboard potentiometer output voltage increases, counterclockwise adjustment potentiometer output is reduced. Double-sided wiring, the bottom of a large area of copper to ensure more excellent heat! Can be rated long-term work in the 2A maximum output power extended to 20W, but also more convenient external radiator output greater power; Input voltage range: DC 3.2V to 46V (input voltage must be higher than the output voltage of 1.5V or more. Can not boost); Output voltage range: DC 1.25V to 35V voltage continuously adjustable, high efficiency (maximum 92%) Maximum output current of 3A; Measured 12V input, 5V output current 1A when the load regulation rate is less than 1%. Voltage regulation: Access the power supply (3-40V), adjust the blue potentiometer knob (generally clockwise rotation boost, counterclockwise rotation buck) and monitor the output voltage with a multimeter to reach the required voltage so far. Weld method: welding, the power cord will be directly welded to the input (output) port; welding pin, you can insert the pin through the lead or inserted in the hole board; or after the direct welding of the PCB on the PCB. Application example: Power supply, only need to connect the module input on the car cigarette lighter power supply, you can adjust the potentiometer, the output voltage can be adjusted at 1.25-30V for your mobile phone, MP3, MP4, PSP and many other devices Power supply, very simple and convenient; To the electronic equipment power supply, when the equipment needs 3-35V power supply and the corresponding voltage power, the use of this module can be easily transferred to the required voltage voltage to solve the problem; System work voltage test, do the project can use this module to debug a variety of voltage test system operating voltage range, very easy and convenient. Precautions: Note Outputs below 2A can be used for a long time without additional heat sink, Output current greater than 2.5A (or output power greater than 10W) Long time work Please add heat sink; Note that the input and output can not be reversed, the reverse may burn; Long time work recommended within 2.5A of the current use, plus the heat sink (10W output); As a result of the buck module, in order to ensure stable output, please maintain a minimum 1.25V pressure difference.
