Discrete Led Driver

LED, constant current source, buck converter This application note describes a 300 mA Discrete LED Driver based on a buck-converter principle, with a cycle-by-cycle current control. It includes a proposal for a BOM and layout of a low cost, low component count solution. This application note describes a 300 mA Discrete LED Driver based on a buck-converter principle with an ef´Čüciency of 80 to 90 %. It includes a proposal for a BOM and layout leading to a low cost, low component count solution to drive a single LED or a string of LEDs connected in series.
