Large Current 5A Constant Current LED Driver

A low-cost high-amperage Switch mode DC/DC Buck supply capable of supporting your power-hungry projects.

This module allows you to get any voltage between 0.8V to 30V (Input voltage must be greater than output voltage)

Features:

• A Bourns 3296 25-turn potentiometer is installed on board to facilitate granular output voltage settings
• Pin spacing of 0.6″ x 1.5″ to easily affix into the 0.1″ pin spacing of most breadboard and perfboard.
• This module is up to 94% efficient.  The higher the output voltage, the higher the efficiency.  The LM2596 datasheet provides more specific details regarding efficiency.
• Up to 3A of supply current.  Depending on input and output voltage, a heatsink should be affixed to the LM2596 (not included)
• Large output range of 0.8V-30VDC
• Low dropout of 1-2VDC, depending on load
• Free 16-pin break-away header strip included!  Only 4 pins are required to be soldered onto the board (pins are left unsoldered in case you need to wire the module). The pins on the header strip can be easily twisted to remove single pins.

Specifications:

• Input voltage: DC 5.2 ~ 32V.
• Output voltage: DC 0.8V ~ 30V continuously adjustable (the input voltage must be higher than the output voltage by 1.5V).
• Output current: max 5A, recommended for 4.5A usage.
• Output power: up to 75W, for more than 50W, please use enhanced heatsink for better heat dissipation.
• Conversion efficiency: up to 96%.
• Load regulation: S (I) ≤ 0.8%.
• Voltage Regulation: S (u) ≤ 0.8%.
• Operating Frequency: 180KHz
• Operating Temperature: -40 ~ +85
• Size: 6.6cm x 3.9cm x 1.8cm.
• With overheat for protection and short circuit protection.

Applications:

• Solar Power Regulator. Can regulate varying PV input to any fixed voltage.
• Robot Power Supply for Digital Circuits (3.3V, 5V, or Adjustable ) and Motor Drivers
• DC Power Supply for Amplifiers
• Compact Low weight power supply for Quadcopter and other flying robots.
• For DC/DC buck module applications the input voltage is higher than the output voltage of the buck field, such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TV, portable instrument power supply,telecom/networking equipment,24V vehicle notebook power supply, industrial equipment buck.12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V, 24V buck to 12V, 36V buck to 24V etc.
