Tiny 4 to 24V DC to Adjustable Output 3A DC DC Buck Converter Module - Twin Pack

Now available from PMD Way is this incredibly tiny DC to DC buck converter module. It has an input voltage range of 4 to 24V DC, and has both an adjustable voltage output and fixed output ranges of:

• 1.8V DC
• 2.5V DC
• 3.3V DC
• 5V DC
• 9V DC
• 12V DC

Naturally the input voltage needs to be greater than the required output voltage. These modules are ideal for replacing classic 78XX-style power regulator-based power supplies in your projects, and will save you time and money. Check out the impressive specifications below.

This buck converter doesn't use electrolytic capacitors, instead - high-quality MLCC-type which last much longer and won't explode. Furthermore, the use of high-current low-resistance inductors on the switchmode converter allow for high efficienct and low-temperature operation. 

Modules are sold in packs of two. Please click here for packs of twenty.
