DC-DC LED Driver IC
Efficiencies up to 98%, dimming level down to 1%, supported by user-friendly design tools
Infineon offers a broad portfolio of highly integrated DC-DC LED drivers that support currents from 150mA to 3A, making them the ideal choice for high- and ultra-high-power LEDs. Efficiency can be as high as 98 percent across a wide range of operation conditions. For the vast majority of buck LED drivers, users have the choice of dimming concepts: PWM or analog voltage. While integrated smart thermal protection, along with overvoltage and overcurrent protection, contribute to a longer LED lifetime.
With the ILD4000 and ILD6000 families Infineon provides highly integrated smart LED buck controllers for high power LEDs. The ILD4000 is the low-cost DC-DC LED driver IC family with a breakdown voltage of 40V and basic thermal protection. The ILD6000 is the feature-rich DC-DC LED driver IC family with a breakdown voltage of 60V and advanced thermal protection.
The controller concept of the of the ILD1150 family allows for multiple configurations such as boost, buck, buck-boost, SEPIC and flyback configuration by simply adjusting the external components. The ILD1151 offers the most flexible dimming options.
