Step-Down Buck Converter

Extra small size AMS1117-3.3 power module, support DC 4.2V-10V to 3.3V 800mA constant voltage output.VIN, OUT, GND 3 pin can be easily connected with your MCU development board, and supply capacitive power supply. Matched with AMS1117-3.3 LDO chip, supply stable low-voltage power supply for all kinds of Arduino / ESP, etc. microcontroller electronic experiment. Can not work above the operating voltage or reverse polarity, otherwise, the module will be damaged easily.

This power supply module is based on the AMS1117 3.3V regulator. It is capable of regulating a wide range of input voltage (4.0 to 12V) down to a fixed 3.3V output at up to 1A (Vin = 4.5V). Standard 0.1″ header pins provide a means of connecting to its input and output terminals.

The Buck Regulator module converts an input of 4.5-40V into a very stable 5V 2A output. The Step-Down Voltmeter device features a USB port through which you can charge your phone. While charging your device please consider that the output of this device is regulated at 5V 2A. Simply connect this device to the power supply, the voltage can be detected in real-time. When you need the phone, IPAD, MP3, and other digital products to charge, click the “Output Enable” button, then the USB power indicator lights up and Variable Power Supply will start supplying 5V 2A at its output. When you need to turn off the voltmeter, click the “Low Power” button, then enter the ultra-low-power standby mode, USB output corresponding shutdown.2A USB Charger accepts wide input voltage as from car/battery car/motorcycle used for monitoring battery voltage; measure the voltage needed for a variety of occasions. The output current capability is 5.0V/2A, enough to meet a variety of USB devices.

This is DC-DC 4.5-40V To 5V 2A USB Charger Step down Converter Voltmeter Module, a combo of 2A Charger and voltage checker.

The module converts an input of 4.5-40V into a very stable 5V 2A output. The device features a USB port through which you can charge your phone. While charging your device please consider that the output of this device is regulated at 5V 2A.

HLK-PM01 5V/3W Switch Power Supply Module is a plastic enclosed PCB mounted isolated switching step-down power supply module. It can supply 5V DC from  120V AC – to 230V AC and has a power rating of 3 Watt. This makes it perfect for small projects that need a 5-volt supply from mains. There are many advantages of these modules, such as low-temperature rise, low power, high efficiency, high reliability, high-security isolation, etc.

MP2307 Mini 360 Step-Down Buck Converter Power Module uses an integrally molded power inductor and synchronous rectifier control chip, smaller and more efficient. This Module can be used as a DIY mobile power, monitor power supply, power buggies, camera power supply, car power, communications equipment supply, various right size and weight for demanding applications (such as aviation models, etc.

The Mini MP1584 DC-DC 3A Adjustable Buck module is an ultra-small adjustable 0.8V to 20V output DC to DC step-down Buck converter that uses an MP1584EN high-frequency switching regulator and integrated high voltage power MOSFET. It features a soft start, thermal shutdown, and under-voltage lockout (UVLO) to protect the module from operating at the insufficient supply voltage. Small size, lightweight, low internal power consumption, and wide input voltage range of 4.5V to 28V makes this module suitable for a variety of different applications where small size and lightweight voltage conversion is needed, including RC cars and airplanes, quadcopters, robotics, Arduino modules, and DIY devices.
