## Description

10 Pieces 5v regulator module mini voltage reducer DC 4.5 - 24V 12V 24V to 5V 3A volt buck converter power supply transformer moduleParameters: Input voltage: DC 4.5 - 24VOutput voltage: integrated adjustable and fixed output, and adjustable range is 0.8 - 17V, fixed output is 1.8V, 2.5V, 3.3V, 5V, 9V, 12V, able to be chosen on the back side. Output current: 3A max, please enhance cooling work when it is full load. When actual tested input 12V and output is 1.5A, no need to add other system. Enable function control: yes, low electric level will stop working when high electric level is working. High electric level is 2-5V, low electric level is 0V or so. Operating temperature: -40℃ - +85℃, industrial class, the higher the operation temperature is, and the smaller the output power is. Conversion efficiency: 97.5%, 6.5V to 5V, 0.7AFrequency: 500KHzOutput ripple: 20 mV, 12V to 5V, 3A, 20M widthOutput over-voltage protection: noTemperature rising range at full load: 40℃Static current: 0.85mAVoltage adjustment rate: -0.5%, 0.5%Dynamic response speed: 5% 200uSOutput short-circuit protection: yes, please don't keep making it short-circuit. Output reverse connection protection: noWiring method: solderingOutput method: soldering or pinsWelding hole spacing: 2.54 mmSize: 20 x 11 x 5 mmPackage includes: 10 x Mini 5v regulators

## Features

- Voltage range: the power supply module input is DC 4.5 - 24V, adjustable range is 0.8 - 17V, fixed output is 1.8V, 2.5V, 3.3V, 5V, 9V, 12V which can be chosen on the back; Output current is 3A max, please increase the cooling work at full load; If the actual test input is 12V and output is 1.5A, no other system is required
- Adjustable and fixed voltage output: this buck converter allows you to get fixed output voltage by soldering the pot on the board, and you can adjust the fixed output voltage by potentiometer as you needed
- Product performance: the voltage regulator module has high efficiency, ultra-compact size, high frequency, low ripple and stable working performance, widely applicable for fixing work: Synchronous rectification and the circuit conversion efficiency is as high as 97.5%
- Reliable material: regulator module is made with quality potentiometer and 3A current chip, high current shielding inductor and MLCC solid capacitor with long service life; High current shielding inductance, ultra-low internal resistance, maximize conversion efficiency, reduce heat generation
- Convenient to use: integrated enable port of the regulator board defaults to working mode and will be closed when it is at low electric level off, and with ultra-low quiescent current, quiescent current is 0.85 mA; It can be connected to the car battery without a switch, cigarette lighter cord or the ACC power cord
