LTC1871 100W Adjustable DC-DC Boost Converter Module

Power your electronic projects with the LTC1871 100W Adjustable DC-DC Boost Converter Module. This high-power step-up converter is designed to increase a lower DC input voltage to an adjustable higher DC output voltage.

With a reported 3.5V–30V DC input range, adjustable 3.5V–30V output range, dual digital voltage display and convenient screw-terminal connections, this module offers flexible voltage conversion for electronics development, DIY power supplies, battery-powered systems and industrial prototyping.

The module is advertised with up to 100W maximum output power. Actual power delivery depends on input voltage, output voltage, available input current, cooling and operating conditions.

Key Features

• Adjustable DC Output: Adjust the output voltage according to your project requirements, within the supported operating range.

• Wide Input Range: Accepts a reported 3.5V–30V DC input.

• High Power Capability: Advertised maximum output power of up to 100W, subject to operating conditions.

• Dual Digital LED Display: Monitor input and output voltage using the onboard display.

• LTC1871 Controller: Uses the LTC1871 current-mode switching controller.

• Screw-Terminal Connections: Convenient IN+ / IN− and OUT+ / OUT− connections.

• Compact PCB Design: Suitable for electronics workbenches, prototyping and custom power supply projects.

• Adjustable Step-Up Conversion: Designed to increase DC voltage rather than reduce it.

Technical Specifications

Input and Output Connections

The module features four clearly identified connection terminals:

• IN+: Positive DC input.

• IN−: Negative DC input.

• OUT+: Positive DC output.

• OUT−: Negative DC output.

Connect the DC power source to the input terminals and the intended load to the output terminals. Verify polarity before switching on the power supply.

How Does It Work?

The LTC1871 boost converter uses switching conversion technology to increase a lower DC voltage to a higher adjustable DC voltage.

For example:

• Convert a 5V DC source to a higher DC voltage.

• Increase a 12V DC supply to a suitable higher voltage.

• Create an adjustable DC power source for electronics testing.

• Supply higher-voltage circuits from compatible lower-voltage DC sources.

The output must remain higher than the input for step-up operation.

Typical Applications

• Adjustable DC power supply projects

• Battery-powered electronics

• DIY electronic equipment

• Embedded system development

• Industrial control prototypes

• LED power supply projects

• Electronics testing and experimentation

• DC voltage conversion systems

• Custom power supply development

Installation and Safety Instructions

1. Check the input voltage before connecting the module.

2. Observe correct positive and negative polarity.

3. Adjust the output voltage before connecting sensitive electronic equipment.

4. Do not exceed the module's specified voltage range.

5. Ensure the input power supply can deliver the required current.

6. Provide adequate ventilation and cooling at higher loads.

7. Use suitable wire thickness and secure terminal connections.

8. Install appropriate input-side fuse and protection where required.

9. Do not assume the module has short-circuit or reverse-polarity protection unless independently verified.

Important Operating Information

The advertised 100W maximum output is conditional. Maximum available output power depends on the input supply, voltage conversion ratio, circuit efficiency and thermal conditions.

The LTC1871 is the controller IC; the complete module's performance depends on the surrounding power components and PCB design.
