Details

The 3.3/5 V super-efficient regulator that snaps right on your 9V battery.

What is snapVCC?

snapVCC is a highly portable and convenient power supply for your electronics projects. It’s designed to fit right on a 9V battery and give you 3.3V or 5V power wherever you need it.

What can you do with snapVCC?

Many circuits require a regulated 3.3 or 5 volt power supply. The 9V battery is an easily available power supply option. A common way to power circuits using a 9V battery is to use a Linear regulator IC circuit to drop the voltage down, as shown below.

Regulator Circuit

snapVCC eliminates this additional circuit by putting the regulator right on top of the 9V battery.

Also, since snapVCC uses a buck converter, it’s more efficient than using a linear regulator.

snapVCC Breadboard

In an emergency you could even charge a simple (non-smart) phone with snapVCC.

(The above uses a home-made USB adapter cable.)

Specifications

  • Texas Instruments TPS560200 buck converter with 500 mA output current
  • 3.3 V / 5 V output, switchable via jumper
  • P-MOSFET for reverse polarity protection
  • Power indicator low power LED
  • Tiny form factor, sits on top of a 9V battery
  • Power headers are standard .1” pitch
  • Comes with a jumper cable for plugging into a breadboard

Features

snapVCC uses a buck converter for efficient regulation of battery voltage. snapVCC has an LED power indicator, reverse polarity protection, and you can switch between 3.3V and 5V by just switching a jumper.

Your breadboard's new best friend. Available as singles, and in packs of two and five for extra savings - in case you need one for every toolbox, or if you want to have extras to share. Free shipping to US and India.
