Features: AC – DC Conversion Double output voltages (Positive – Ground – Negative) Adjustable positive and negative rails Just a Single-Output AC transformer Output noise (20MHz-BWL, no load): Around 1.12mVpp Low noise and stable outputs (ideal to power Opamps) Output Voltage: +/-1.25V to +/-25V Maximum output current: 300mA to 500mA Cheap and easy to solder (all component packages are DIP) A double output low noise power supply is an essential tool for any electronics enthusiast. There are many circumstances that a double-output power supply is necessary such as designing pre-amplifiers and powering OPAMPs. In this article, we are going to build a linear power supply that a user can adjust its positive and negative rails independently. Moreover, just an ordinary single-output AC transformer is used at the input.

A tiny DC to DC buck converter board is useful for many applications, especially if it could deliver currents up to 3A (2A continuously without heatsink). In this article, we will learn to build a small, efficient, and cheap buck converter circuit.
