DC-DC Buck Converter Module from 5V-32V to 0.8V-30V Battery Charger / Current / Voltage Driver for LED 5A

Description

What it is

The DC-DC Buck Converter ARD0011121 is an electronic module that allows converting a DC (direct current) power supply with an input voltage range of 5 V to 32 V into an adjustable output voltage range of 0.8 V to 30 V.

Features

• Input Voltage: 5 V – 32 V
• Adjustable Output Voltage: 0.8 V – 30 V
• Maximum Output Current: 5 A
• SKU: ARD0011121
• Price: 5.45 €

What it is for

This regulator is ideal for powering electronic circuits that require a different voltage than the main power supply. It can be used to charge batteries, regulate voltage for LEDs or other electronic components, and can be integrated into Arduino and 3D printing projects. For example, it can be used to charge a 3S LiPo battery (11.1V) with the output voltage set to 3.7V.

Tutorial: How to use DC-DC Buck Converter ARD0011121

The DC-DC Buck Regulator ARD0011121 is ideal for charging batteries and regulating voltages, perfect for beginner electronics and maker projects.

What you need

• Multimeter
• Craft Knife
• Test Lead
• LiPo Battery (optional)

Steps

1. 1. Check that the input voltage (5-32 V) is correct with the multimeter.
2. 2. Connect the positive lead of the input voltage to the V_in pin.
3. 3. Connect the negative lead of the input voltage to the GND pin.
4. 4. Set the output voltage (0.8-30 V) with the resistance on the V_set pin.
5. 5. Connect the positive lead of the output voltage to the component to be powered.
6. 6. Connect the negative lead of the output voltage to the GND.
7. 7. Check the datasheet for the maximum current (5A) to avoid damage.
8. 8. Test the regulator with a small resistance (100 ohm) to verify the output voltage.

Mini project

Charge a 3S LiPo battery (11.1V) with the output voltage set to 3.7V.

Common mistakes

• Connect the negative lead to GND only after verifying the maximum current.
• Set the output voltage too high relative to the load resistance.
• Do not use a load greater than the maximum allowed current.
• Do not use input voltages higher than 32V.

Recommended accessories

• 3S LiPo Battery
• Load resistance
• Multimeter
• Thermal dissipation bag (optional)

Frequently asked questions

Can I use this regulator with an input voltage of 32V?
Check the datasheet for the maximum input voltage.

How long does it take to charge a battery?
The charging time depends on the charging current and the battery capacity.

Can it regulate the output voltage to 0V?
Check the datasheet for the minimum output voltage.

What should I do if the regulator does not regulate the voltage correctly?
Check the connections and resistance on the V_set pin. Check the datasheet for the output current.
