DC/DC LED Driver The DC/DC LED drivers consist of two main product families: The BCR series is the smallest size and lowest cost product family for linear LED drivers. The ILD series are switch-mode LED drivers with highest efficiency. Both families come with a line-up of regulators with integrated power stage and with a line-up of controllers that allow utmost scalability by flexible dimensioning of the output stage. Family Overview of DC/DC LED Drivers for General Lighting Applications ILD6150 ILD4001 + Switch ILD4120 ILD6070 SELV Isolation * max. 45V in Boost and SEPIC conguration **...

The ILD switch-mode LED drivers, on the other hand, support currents from 150mA to 3A, making them the ideal choice for high- and ultra-high power LEDs in general lighting applications. The voltage management is very flexible for the selection of the topology: buck, buck/boost, boost and SEPIC configuration are supported. Efficiency can be as high as 98% across a wide range of operation conditions. For the vast majority of buck LED drivers the user has the choice of dimming concepts: PWM or analog voltage. Integrated smart thermal protection, over voltage and over current protection...
