Here is a look back of Allegro’s A8515, a wide input voltage range, high efficiency fault tolerant white LED driver. The device was made available in the market since 2010. It features multiple output ...

This article is excerpted from Section 21 of “Analog Circuit Design: Volume 3 – The Design Note Collection,” (ISBN: 978-0-12-800001-4), edited by Bob Dobkin and John Hamburger of Linear Technology ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

High-brightness LEDs are an inexpensive, robust, and green replacement for halogen light bulbs. This Idea for Design shows you how to apply an AC LED driver to convert the usual 12 or 24 V AC ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as ...

A VFD reports a low-volts fault when the drive's dc link voltage drops below 62% of the nominal level for the high setting (480 Vac) and 50% of nominal for the low setting (400 Vac). The +10% and -15% ...
