Guidelines for reading an optocoupler datasheet

Electronics News Updates / Ibrar Ayyub

Introduction Optocouplers, also known as opto-isolators, are components that transfer electrical signals between two isolated circuits by using infrared light. As an isolator, an optocoupler can prevent high voltages from affecting the side of the circuit receiving the signal. Transferring signals over a light barrier by using an infrared light-emitting diode and a light-sensitive product, […]

Waffle implant supplies drugs

Blog, Electronics News Updates / Ibrar Ayyub

An implantable, microchip-based device may soon replace the injections and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable, microchip-based devices that store and release drugs inside the body over many years. Invented by Microchips Biotech co-founders Michael Cima, the

Simplify DC-DC Converter Characterization

Electronics News Updates / Ibrar Ayyub

DC-DC converters are widely used components that convert DC power from one voltage to another, producing a regulated output voltage. These devices are used in many electronic products, including laptops, mobile phones, and instrumentation. Like any device, DC-DC converters need to be characterized by manufacturers and by engineers evaluating them for a design. Given the
