## Overview

The DollaTek ADJ Power Module is a high-efficiency DC-DC buck regulator featuring adjustable output voltage from 1.25V to 35V and a maximum output current of 3A. Built with a HW-411 chip and manufactured using advanced machine placement and reflow soldering, it delivers up to 92% efficiency. Designed for reliability, each unit undergoes a 2-hour aging test. Its wide input voltage range (3.2V-40V) and compact design make it ideal for professional-grade electronics projects requiring stable, customizable power supply.

## Description

Description: 1. HW-411 chip module uses high quality, high efficiency (up to 92%), heat up a small, can easily set up 3A (short) on, long working hours current is recommended for use in less current of 2.5A, while adding fins (10W output above). 2. This module uses machine placement, reflow welding, and each module before shipment after two hours of aging test, to ensure high reliability. 3. Input voltage range: DC 3.2V-40V (input voltage output voltage must be greater than 1.5V or several Cannot increase.) 4. Output voltage range: 1.25V-35V DC voltage is continuously adjustable, high efficiency (up to 92%), maximum output current of 3A. Note: 1. Long working hours is recommended for use in less than 2.5A current, while adding a heat sink (10W output above); due buck module, in order to ensure stable output, maintain a minimum differential of 1.5V. 2. This module is adjustable buck module; the module can be adjusted above blue adjustable damping resistance to change the output voltage. Input and output pressure is 2V; the minimum can be the output voltage of 1.25V. 3. The above indicated modules IN- (negative input), IN+ (positive input), OUT- (negative output), OUT + (positive output) make sure you choose the right one, otherwise it may cause damage to the module. 4. This module has no output short circuit protection, output short circuit if extended, may cause damage to the module. The contents of the box 1 x DollaTek ADJ Power Module
