Description

HUAREW / DC-DC step-down converter regulated power supply module.
Input voltage: 3.2V~35V
Output voltage: 1.25 V ~ 35 V.
Output current: 3A (max.)
Conversion efficiency: 92% (highest)
Output ripple: <30mV.
Switching frequency: 65 kHz.
Working temperature: -45°C ~ +85°C.

Wiring
1. Welding, direct welding of the power cord to the input (output) connection;
2. Solder the pins that can be inserted into the pins through the wires or inserted into the perforated plate for use;
or soldered directly to the board after adding the pins.

Example of use:
1. Vehicle-controlled power supply, you just need to connect the input end of this module to the cigarette lighter of the car to provide power,
You can adjust the potentiometer, and the output voltage can be adjusted arbitrarily between 1.25 and 30 V to charge your mobile phone, MP3, MP4, PSP, etc.
Powered by many devices, very simple and convenient.
2. Power supply for electronic devices. If the device requires a 3-35V power supply and the corresponding power supply,
This module can easily adjust the voltage to the required voltage and solve the problem.
3. System working voltage test, you can use this module to debug the working voltage range of different voltage test systems when you perform projects, which is very easy and convenient.
Includes:
5 x step-down converters
