Flyback topology offers superior balance in LED drivers

摘要

LED-based light fixtures and bulb replacements are now rapidly replacing incandescent, halogen, and CFL (compact-fluorescent-lamp) light sources in many general-lighting applications. Flyback dc/dc converters are the power-supply topologies of choice for a large segment of the LED-driver market because these devices allow electrical isolation between the LEDs and the ac line, which is a safety requirement in most LED lamps.
