Power Adapter Module for DIY projects, 3.3V DC-DC converter

Perfect 3.3V power adapter module for use with breadboards. 

DC-DC converter that reduces the voltage from up to 18V to 3.3V.

This is a switching step-down converter. In comparison with dropout converters:

• Energy-efficient
• Compact
• Reliable
• Have additional security features
  
  

Incredible size - 0.5"x0.3" (13x8mm) allows you to place it in any project. If you need to get a full power up to 1A, you may need to attach a heatsink. In my tests, I used a 15x20x9mm aluminum MOSFET heatsink.

Features: 

• 3.3V power output
• 4.8-18V power input
• 1A max load (When used heatsink)
• 700mA nominal load (12V input)
• Power-good indication LED
• Input power indication LED
• Shor-circuit protection
• Overheat protection
• Reverse polarity protection

Important Safety Note: 

Handle carefully! Hot surfaces!
When the output current exceeds 750mA, the temperature of some PCB components may reach 230°F (110°C). When the output current is 500mA, the temperature may reach 170°F (75°C)
