Infineon Technologies has introduced an LED driver IC, the ILD8150/E, that features an innovative hybrid dimming mode technology for achieving 0.5% of the target current. With its supply voltage range from 8 V DC up to 80 V DC, the driver IC provides a high safety voltage margin for applications operating close to safe extra-low voltage (SELV) limits. The driver IC is well suited for general and professional LED lighting applications with high dimming requirements.
Infineon’s new ILD8150/E drives up to 1.5 A using a high-side integrated switch. The latter one with a low R DS(on) of 290 mΩ (ILD8150) enables high power designs with an efficiency of more than 95 percent. It incorporates a soft-start function to protect the primary stage from abrupt current requests and a shunt resistor for adjustable maximum output current. Precise output current accuracy of typical 3 percent from one device to another under all load and input voltage conditions makes the IC perfect for e.g., tunable white and flat panel designs where current must be identical. Additionally, under voltage lockout (UVLO) for the bootstrap voltage and over temperature protection functions provide an ideal fit for professional LED lighting solutions.
The LED driver IC is packaged in a DSO-8 housing which enables wave soldering. Higher thermal performance can be achieved with the ILD8150E in a DSO-8 package with an exposed pad.
