DC5-36-TO-DC3V3-5 User Guide

Overview

Product overview

DC5-36-TO-DC3V3-5 is a compact DC-DC buck regulator module with a wide voltage input range, capable of switching between 3.3V and 5V output voltages

Features

Supports a wide voltage input of 5~36V, with the ability to set the output to 5V or 3.3V, and the output current can reach 4A
- The factory default is 5V output, and the input voltage range is: 6~36V
- Can be set to 3.3V output by soldering, and the input voltage range is: 5~36V
3.3V or 5V buck-regulated regulated output, which can be selected by welding the switching resistor
Adopts black immersion gold process, small in size and easy to integrate and embed

Version Options

SMD version With header and terminal

Basic function

Using the DC5-36-TO-DC3V3-5 as a buck regulator module, it is connected in series between the power supply and the device, and can also be embedded in other products, thus realizing the reduction of input voltages ranging from 5V to 36V to 3.3V or 5V output voltages. The output voltage can be changed by soldering a switchable resistor
