Mini 3A 0.8-20V Output MP1584 DC-DC Adjustable Step-Down Buck Power Supply Module

  • $1.59

This ultra small adjustable 0.8V to 20V output DC to DC step-down Buck converter uses an MP1584EN high frequency switching regulator and integrated high voltage power MOSFET. 

It features soft start, thermal shutdown, and under-voltage lockout (UVLO) to protect the module from operating at insufficient supply voltage.

Small size, light weight, 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.
