## Overview

The XLX 8A DC-DC Buck Boost Converter is a high-efficiency, adjustable power module designed for stable voltage and current output across a wide input range (5-30V). Featuring synchronous rectification technology, dual heat sinks, and comprehensive protection mechanisms, it supports up to 20A output current and is ideal for automotive, solar, LED, and industrial applications.

## Description

Module character: Non-isolated synchronous rectification automatic buck-boost module Input voltage: DC5-30V Input current: 8A (MAX) peak 10A (within 6A for long-term operation) Static working current: 4mA (there will be errors when the working voltage is different) Output voltage: 1.25-30V continuously adjustable Output current: 10A (MAX) (within 5A natural heat dissipation for a long time, please derate for high voltage output)Please use additional heat dissipation or derating if the module temperature exceeds 65 degrees Output constant current range: 0.2-10A Working temperature: -40 ~ + 85 degrees Working frequency: 150KHz Conversion efficiency: typical 91% up to 93% Overcurrent protection: Yes Short circuit protection: Yes (current limiting protection) Over temperature protection: Yes (the output voltage is automatically reduced after over temperature) Input reverse connection protection: None, (if necessary, please insert a diode in the input) Output anti-reverse: Yes, no anti-reverse diode is needed for charging. Wiring mode: terminal output (IN is input, OUT is output) Module size: 60mm * 53mm * 22mm (length, width, height) Package Included: 1PCS * High-power Buck Converter Step-down ModuleApplication: This module can be used in areas with large input voltage fluctuations and relatively stable output requirements. Such as: 1. 12V battery (10-14V) stabilized output 12V, power 12V equipment, 24V battery stabilized 24V; can be used as vehicle power supply. 2. Solar panel voltage stabilization. The voltage fluctuation of solar panel is relatively large. This module can stabilize the output, power the equipment or charge the battery. 3. Drive high-power LED lights and constant current drive. For example, 12V battery drives 4 string LED lights. At this time, there is not much difference between LED and battery voltage.

Review: Works great to float charge my car battery with limited current.
Review: I bought this buck/boost converter after trying several other unreliable converters (others failed to hold their output voltage steady under load, and/or dipped/spiked in voltage after power-on). This buck/boost converter seems to give a very robust and stable voltage output compared to the others, so finally my search is over. However, there's a good reason why there are two big heatsinks on this unit (and why I'm giving it 4 stars): it gets very hot to the touch, even when operating well under-spec. I'm dropping 29V input to 24V@1A, and I'm concerned about the temperature both heatsinks are reaching. I may need to mount a cooling fan.

## Features

- Super material: It is made of electronic accessories, nickel plating on surface(anti-oxidatioan), inner conductor: pure copper.it is long lasting and durable for you to use.
- Package including: 1 Pack of Constant Current Voltage Step-up Module. Moreove. The buck module has 2 heat sinks that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current. With LED indicator, more stable and reliable to use.
- Input and output: With a wide input voltage range from 5-30V, Input current: 8A (MAX) peak 10A (within 6A for long-term operation. Output Current: 20A(max.), 15A (suggested).Output voltage: 1.25-30V continuously adjustable Output current: 10A (MAX) (within 5A natural heat dissipation for a long time, please derate for high voltage output). Output constant current range: 0.2-10A Working temperature: -40 ~ + 85 degrees.
- Synchronous rectification technology: Synchronous rectification uses a dedicated power MOSFET with very low on-resistance to replace the rectifier diode to reduce rectification losses. It can greatly improve the efficiency of DC / DC converters. The synchronous rectification technology is to greatly reduce the rectification loss at the output end of the switching power supply, thereby improving the conversion efficiency and reducing the heating of the power supply itself.
- A wide range of applications: Widely uses in power transformer, DIY adjustable power supply, LED car display, mobile power, industrial equipment appliances, LED driver, monitor, solar energy, fan, battery conversions, micro-controllers, and electronic projects. so on. Maintain stable output voltage and limit the output current over a range of input voltages.

### ⭐⭐⭐⭐ Review
*by Q***N on 29 August 2025*

I was a little worried at first with using it on my Raspberry pi or my Jetson nano for noise on the output, but after using them for multiple hours with no noticeable temp difference from feel. I was less worried, after a little bit I did add on some capacitors on the output just to be safe but voltage was holding accuretly even while my batteries were dying.
