INFINEONILD8150XUMA1ILD8150XUMA1 LED Driver IC, 18 V dc 1.5A 8-Pin PG-DSO-8

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.

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
