Strengthening the link between the real and the digital world
Best-fit components for high-power LEDs
Besides efficiency and current accuracy, the main features in highest demand for DC-DC LED driver ICs are analog and PWM dimming and thermal protection of the LED system. Despite the high efficiency of LEDs, it is important to remember that nearly 60% of all energy supplied to LEDs converts to heat. Exposure to high temperatures significantly decreases LEDs’ lifetime, eliminating a key value proposition for purchasing an LED fixture. The value proposition from Infineon LED driver IC’s is a gradual reduction of the LED current which increases the lifetime and reliability of the LED system.
Semiconductors that enhance high-power LED designs
Infineon offers a broad portfolio of DC-DC LED driver ICs that supports currents between 150 mA and 3 A, making them the ideal choice for high- and ultra-high-power LEDs in general lighting applications. For buck topology, the ILD4000 and ILD6000 families are the best fit. Meanwhile, the ILD1150 family supports buck/boost, boost and SEPIC configurations.
If the budget is your main concern, there’s ILD4000, the low-cost DC-DC LED driver IC family with a breakdown voltage of 40 V and basic thermal protection. For customers requiring many features, discover ILD6000, the feature-rich DC-DC LED driver IC family with a breakdown voltage of 60 V and advanced thermal protection. Its trigger point for thermal protection is also especially easy to adjust. Your design’s efficiency can be as high as 98% across a wide range of operation conditions. Most buck LED drivers give your customers the choice between analog or PWM dimming.
