LM2596S with SMD LED DC-DC Step-Down Power Supply

DC-DC Buck Converter Step Down Module LM2596 Power Supply is a step-down(buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version.

The LM2596 series operates at a switching frequency of 150kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators.

This is an LM2596 DC-DC buck converter step-down power module with the high-precision potentiometer, capable of driving a load up to 3A with high efficiency, which can work with Freeduino UNO, other mainboards, and basic modules. When the output current keeps greater than 2.5A (or output power greater than 10W), please add a heat sink to it.

This device is internally compensated to minimize the number of external components to simplify the power supply design.

Since LM2596 converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages. The LM2596 operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.

Features:

1.   Input voltage:3-40V.

2.   Output voltage:1.5-35V(Adjustable)

3.   Output current: Rated current is 2A, maximum 3A (Additional heatsink is required)

4.   Module Properties: non-isolated constant voltage module

5.   Rectification: non-synchronous rectification

6.   Short circuit protection: current limiting, since the recovery

Product Description:

• The MT3608 2A Max DC-DC Step Up Power Module Booster Power Module is a low-cost module that can step-up a 2 to 24V input voltage up to a 5 to 28V output at up to 2A.
• DC-DC boost converters step up the input voltage to a higher voltage while also stepping down the available current since the module can’t output more power than its inputs.
• This boost converter is adjustable and capable of outputting a voltage in the range of 5.0 to 28V at a continuous current of up to 1.5A depending on input/output voltage settings with 1A available with most settings.
• Since it is a boost converter, the input voltage must be lower than the output voltage.
• The device is able to use low ESR bulk ceramic capacitors rather than electrolytic caps which avoids long-term aging concerns and contributes to the compact packaging.
• The MT3608 converter IC has over-current and thermal limiting features built-in to safely shut the device down if driven too hard.

• It’s efficient by up to 93%.
• It can source a good amount of current.
• It is an inexpensive converter module.
• It’s simple to adjust to get your desired increase in voltage.

• These are compact boards with 4 solder pads for making connections.

400W 15A DC-DC Boost Converter Step-up Module is a handy power accessory board that allows you to fine-tune the amount of power your project receives.

This converter can take an input voltage of anywhere from DC 8.5V-50V which can then be regulated to an output voltage between 10-60V continuously adjustable. With a wide input voltage range from 8.5V-50V, the Step-up converter can accurately adjust the output voltage and current. 

The Boost module has 2 heat sinks that could enhance heat dissipation. Wiring is convenient with these large current 15A screw terminals.
