The Infineon ILD8150 is a 80V DC-DC converter IC, designed to drive high power LEDs. For applications operating close to safe 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 ideal fit for professional LED lighting.
Efficiency values of more than 95% Maximum duty cycle up to 99% Up to 2 MHz switching frequency Soft-start Hybrid dimming input with 250Hz to 20kHz PWM dimming frequency Analog dimming 100 to 12.5% PWM dimming 12.5 to 0.5% with 3.4kHz flicker-free modulation Dim-to-off Adjustable max. output current via shunt resistor Typical 3% output current accuracy Overtemperature protection Pull-down transistor to avoid LED glowing in dim-to-off
