NerO – An Energy Efficient Arduino UNO Compatible Design

Background. This project started out as an accessory for another planned KickStarter project - a smart TFT display for Arduino called CleO. Now, the display itself required 150mA current, fine, but when you add a camera with its LED lights, this goes up to 250mA and if you have 1W audio playing simultaneously, unlikely,but possible, then it would require 450mA of current at 5V in order to guarantee operatio ...

Dual 3A PSU on a Chip

Intersil have introduced a single chip just 9 x 6.5 mm which contains just about all the control features (including the output stages) needed to build a dual 0.8 to 5 V power supply with 3 A per channel output capability. The ISL8203M can also supply 6 A in current sharing operation. The ISL8203M is an integrated step-down power module optimized for generating low output voltages down to 0.8V.  The input s ...
