Beschreibung

This reference design board features ILD8150E, a 80V LED driver IC with an innovative hybrid dimming method. For applications operating close to safety extra low voltage (SELV) limits it provides a high safety voltage margin. The buck LED driver IC is tailored for LEDs in general lighting applications with average currents up to 1.5A using a high-side integrated switch. Several performance and protection features provide the right fit for professional LED lighting.The reference design ILD8150 provides flexibility to be used up to 1.5A with a short duty cycle. The hysteretic current control is extremely fast and always stable without the need for any loop compensation. It is suitable for applications with a wide range of supply voltages from 8 to 80V, which gives a clear advantage and flexibility comparing to existing 60V solutions.ILD8150E operates in hybrid dimming mode that helps to minimize LED color shift and audible noise. In range of 12.5 to 100 percent it operates in analog dimming mode, in 0.5 to 12.5 percent in PWM mode with fixed output frequency.ILD8150 provides high accuracy over all conditions, as well as AC 100 or 120Hz input flicker rejection in the whole dimming range.
