Dual 5V + 3.3V Switching Voltage Regulator

We developed this dual 5V and 3.3V Switching Voltage Regulator board to provide efficient power for many accessories. Unlike inefficient linear voltage regulators (which dissipate power via heat), this switching regulator is battery friendly!

This device has 2 power input terminals. They are dioed-or'd together, so that only the highest voltage is powering the device. In this configuration a device can be powered by somehting like a 9.6V battery, and when the battery gets low, a 12V AC/DC adpater can be attached, so that the battery can be unplugged and charged without interupting the devices under power.

This device has 2 output terminals. They are rated at 2.5A each, and can be ordered as two 5V outputs, two 3.3V outputs, or a 5V and a 3.3V output on the same board. You must specify the configuration you desire below.

These are NOT isolated from each other because they share a common ground.

Please note that due to the customization of this product, it could require 3 additional days for order processing.

FYI: Switching regulators typically operate at 85% efficiency, whereas linear regulators typically operate at 40% efficiency.
