This is a DC-DC step-up converter based on LM2585-ADJ regulator manufactured by Texas Instruments. This IC was chosen for its simplicity of use, requiring minimal external components and for its ability to control the output voltage by defining the feedback resistors (R1,R2). NPN switching/power transistor is integrated inside the regulator and is able to withstand 3A maximum

Extending battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs, Microchip has announced a linear Low Dropout (LDO) regulator. With an ultra-low Iq of 250nA versus the approximate 1uA operation of traditional devices, the MCP1811LDO reduces quiescent current to save battery life, enabling end-users to recharge or replace batteries less often. The

Modular DC-DC switching voltage converters (or voltage regulators) are fully integrated devices that take away most of the complexity of power supply design — but not all. One of the key areas that are still left to the design engineer’s discretion is the choice of components for, and layout of, the energy storage and filtering

This project is an independent fan speed regulator that automatically adjusts the speed of an electric fan based on real-time feedback. The use of embedded system technologies like a microcontroller and closed-loop control architecture enables successful and reliable temperature regulation. The ATMega8/168/328 microcontroller allows for rapid adjustment of fan speed based on real-time sensor information.

Proper reflow oven maintenance can extend its life cycle, keep the machine in good condition, and improve production efficiency and product quality. One of the most important tasks for properly maintaining a reflow oven is remove the built-up flux residue inside the oven’s chamber. Although there is a flux collection system in modern reflow machines, there still is a
