Understanding isolated DC/DC converter voltage regulation

Electronics News Updates / By Ibrar Ayyub

Introduction Isolated DC/DC converters are required in a broad range of applications including power metering, industrial programmable logic controllers (PLCs), insulated-gate bipolar transistor (IGBT) driver power supplies, industrial fieldbus, and industrial automation. These converters often are used to provide galvanic isolation, improve safety, and enhance noise immunity. Moreover, they can be used to generate multiple […]

A tiny laser cutter using Arduino

Electronics News Updates / By Ibrar Ayyub

Step 1: To Begin The basis for Groover’s axis was the two mini stepper motors from the DVD-RW drives. The motors drive the DVD head mechanism which either moved the laser cutting head, or the cutting table. My first starting point was to find a similar set of motors, and a reclaimed laser diode. However

Minimizing power consumption when sensing switch inputs

Electronics News Updates / By Ibrar Ayyub

A switch input is one of the simplest interfaces to an MCU. However, when very low power designs are needed the pullup or pulldown resistor for the switch can draw a significant current. If the switch input is a momentary switch the current flow is very short so it is rarely significant. However, if the
