描述 Description

The 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.
