Here is a look back of Allegro MicroSystems’ A8521 released since 2013. The A8521 is a highly efficient fault tolerant white LED driver providing multiple output, features wide input voltage range, ...

LED replacement bulbs include integrated driver electronics employing a variety of circuit topologies. But LED light fixtures frequently require standalone LED power supplies, sometimes called modules ...

Each channel of Linear Technology’s LT3797 triple-output dc-dc controller drives a wide range of LED power in either step-up, step-down, or SEPIC topologies. Its fixed-frequency, current-mode ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

This document is a design example report of a 40 W wide range dimmable, high efficiency, power factor corrected, non-isolated buck LED driver employing LYTSwitch-7 LYT7504D. It operates at an input ...
