DC-DC Converter 15A 400W Step Up Buck Boost Notebook Charging Module

This 400W DC-DC converter module lets you step up voltage from a wide range of input sources to power your devices. It is designed for projects that need a reliable boost converter with adjustable output and constant current control.

This non-isolated step-up module accepts an input voltage from 8.5V to 50V DC. It delivers a continuously adjustable output voltage from 10V to 60V, making it suitable for charging notebooks, powering LED lights, or running other DC equipment. The module supports a maximum input current of 15A and offers a constant current range from 0.2A to 12A, giving you precise control over your power delivery.

Built for efficiency, the converter achieves up to 96% conversion at a 150KHz operating frequency. It includes overcurrent protection to help safeguard your connected devices. The compact design measures 67mm x 48mm x 28mm (2.6 x 1.9 x 1.1 inches) and weighs just 60g (2.1 oz), so it fits easily into enclosures or project boxes.

Key Features and Benefits

- 400W boost capability that provides substantial power for high-demand applications like notebook charging

• Wide input voltage range (8.5V-50V) that works with various power sources including batteries and solar panels

• Adjustable output voltage (10-60V) that lets you tailor the power to your specific device requirements

• Constant current control (0.2-12A) that protects sensitive loads by limiting the current flow

• High conversion efficiency up to 96% that reduces energy loss and heat generation

• Overcurrent protection that automatically shuts down the module to prevent damage during faults

Who Is This For

- DIY electronics enthusiasts building custom power supplies or battery charging stations

• Technicians and engineers needing a versatile boost converter for prototyping or repairs

• Hobbyists working on solar power systems, LED lighting arrays, or portable device chargers

• Anyone who needs to step up a lower DC voltage to power a notebook or other 10-60V equipment

Usage Scenario

Mark was building a portable power station for camping. He had a 12V lithium battery but needed 19V to charge his laptop. He connected the battery to this DC-DC converter, adjusted the output to 19V, and set the current limit to 3A. The module powered his laptop reliably for hours, and the overcurrent protection gave him peace of mind when plugging in different devices.

Micro Comparison

Unlike basic fixed-voltage converters, this module offers both adjustable output voltage and constant current control. This flexibility makes it a better choice for projects where you need to power different devices at different voltages without buying multiple converters. The 400W power rating also handles higher loads than many smaller boost modules.

Questions and Answers

Question: Can this module charge a 12V lead-acid battery?

Answer: Yes, you can set the output voltage to around 14.4V for charging a 12V lead-acid battery, but you must set the constant current limit to a safe level for your battery size.

Question: Does this converter have reverse polarity protection?

Answer: No, the module does not include input reverse polarity protection. Be careful to connect the input wires correctly to avoid damage.

Question: What is the maximum output current at 48V?

Answer: The constant current range is 0.2-12A, but the actual output current depends on the input voltage and power draw. At higher output voltages, the available current decreases due to the 400W power limit.

Question: Can I use this module to power a 48V LED light strip from a 12V battery?

Answer: Yes, you can adjust the output voltage to 48V for your LED strip. Make sure the total power draw does not exceed 400W and that the input current stays below 15A.

Question: Does the module come with a heatsink?

Answer: The package includes only the converter module. For currents above 8A, you should add forced air cooling or a heatsink to prevent overheating.
