## Overview

The Alcoa Prime DC-DC Buck Converter is a compact, high-performance step-down power module delivering up to 9A and 300W. It features a wide input voltage range (7-40V) and continuously adjustable output voltage (0.8-28V), making it ideal for LED drivers, battery charging, and vehicle power supplies. Precision current sensing and low ripple output ensure stable power delivery, while its small size fits perfectly in professional and DIY projects. Cooling is recommended for sustained high loads.

## Description

Applications: 1. High-power LED driver. 2. Lithium battery(or lead accumulator) charge. 3. Vehicle-mounted power supply. 4. Low voltage system power supply. 5. 6V, 12V, 14V, 24V battery charge. 6. On-board laptop power supply. 7. regulated power supply. 8.Low voltage power supply system.DIY or other work requirements Battery charge: 1. Make sure of the battery float voltage and charging current that you need, as well as the input voltage of the module. 2. Adjust the constant voltage potentiometer and adjust the output voltage to about 5V. 3.Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make the output current to the expected charging current value. 4. Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage. 5. Connected to the battery, try to charge. (1,2,3,4 steps to connect the power module input,output no-load does not connect battery.) LED constant current drive: 1. Make sure the operating current and Max operating Voltage of the LED you need to drive. 2. Adjust the constant voltage potentiometer, adjust the output voltage to about 5V. 3. Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected LED operating current. 4. Adjust the constant voltage potentiometer to make the output voltage reach the maximum LED operating voltage. 5. Connect LED, test. (1,2,3,4 steps to connect the power module input, output No-load does not connect LED.) Package Included: 1X DC CC 9A 300W Step Down Buck Converter

Review: In depth usage, yet to be tested! - Brand new, working circuit with good enough components has been delivered by this seller, although there was no brand packaging or else was available. Though this type of buck converter is a generic one, among various sellers. All in all allianzte alcoa prime can be trusted. Further updates regarding usage and application will be shared. This one is going to be used for converting 19v (from laptop charger) to 12v (11.1v) DC to be fed to the laptop through battery charging port. My laptop's power jack broke off from the motherboard, thats why i am trying to power the laptop through battery terminals directly.
Review: Best suited for battery charging - Costly. Working as per my reguirment,can set voltage and current easily depending upon the battery type,tested upto 5amps load

## Features

- Use a dedicated benchmark IC, and high-precision current sensing resistor, High output current, the max output current can reach 9A
- Input voltage: 7-40V Output voltage: 1.2-35V(continuously adjustable) Output Current: 8A (power tube temperature exceeds 65 Degree C please add cooling fan)
- Output Power: Maximum power is about 300W (power tube temperature exceeds 65 Degree C please add cooling fan) Size: Approx. 2.55 x 1.88 x 0.94inch / 6.5 x 4.8 x 2.4cm (Length x width x thickness). Low output ripple , high frequency capacitor reduces output ripple. Suitable for LED driver

### ⭐⭐⭐⭐⭐ Nice product.
*by H***. on 4 October 2022*

This 300 watts buck converter is very helpful. I made a variable bench Power supply and it's still working flawlessly without any problem. But please improve your packaging. I used to order lots of products from Amazon but the packaging was always the drawback. Otherwise, I love Amazon.
