5V – Input 12V + – Output 12V, 5V to + -12V 100mA DC-DC Converter Board

Description

What it is

The DC-DC converter from 5V to ±12V is an essential tool for electronic projects that require an output voltage different from the power supply. This device transforms a 5V input into two outputs of +12V and -12V, providing a maximum output current of 100mA for each channel.

Features

• V_in: 5V
• V_out positive: +12V
• V_out negative: -12V
• Maximum output current: 100mA per channel

What it is for

Projects that require both positive and negative voltage, such as RGB LED drivers or audio circuits, can benefit from this converter. It is ideal for beginner and intermediate makers working with Arduino or other microcontrollers.

Tutorial: How to use DC-DC Converter 5V to ±12V

This DC-DC converter allows generating positive and negative voltages from a positive power supply, useful for projects requiring both +12V and -12V. Ideal for beginner and intermediate makers working on electronic circuits.

What you need

• DC-DC Converter 5V to ±12V
• Power connectors
• Arduino or microcontroller interface
• Electronic components to power

Steps

1. Connect the 5V power supply to the DC-DC converter.
2. Check that power signals are present on the +12V and -12V pins.
3. Connect the circuit or component that requires ±12V.
4. Adjust the voltage if necessary (check the datasheet).
5. Test the outputs with a multimeter to ensure they are correct.

Mini project

Create a simple control interface to adjust the LED RGB lighting level, using ±12V to power the drivers.

Common mistakes

• Do not check the voltage at the outputs before use.
• Omit robust power connectors.
• Use a circuit that requires more current than is available (check the datasheet).
• Ignore the common ground signal between +12V and -12V.

Recommended accessories

• JST-XH connector for 5V power supply
• High precision PWM LED driver
• Digital multimeter
• Arduino Uno interface
