Infineon ILD8150

The ILD8150 is a 80 V DC/DC converter IC for LED applications to drive high-power LEDs. For applications operating close to 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 1.5 A using a high-side integrated switch. A complete set of features and protections provide a well fit for professional LED lighting solutions.
