Infineon REF_ILD8150_DC_1.5A_SMD Buck Regulator for ILD8150E 80V LED Driver IC for LED Driver

The Infineon Reference board ILD8150 80V high-side buck LED driver IC with hybrid dimming. This reference design board features ILD8150E, a 80V LED driver IC with an innovative hybrid dimming method. The LED driver IC provides a high safety voltage margin, especially for applications operating close to safety extra low voltage (SELV) limits. Several performance and protection features provide the right fit for professional LED lighting. The reference design of ILD8150E comes with hysteretic current control, which is extremely fast and always stable without the need for any loop compensation. Additionally it provides flexibility to be used up to 1A with a short duty cycle.
