Infineon Technologies’ new LED driver, the ILD8150/E, features an innovative hybrid dimming mode technology for achieving 0,5 percent of the target current. With its supply voltage range from 8 V up to 80 V d.c., the IC provides a high safety voltage margin for applications operating close to safe extra-low voltage (SELV) limits. It is well suited for general and professional LED lighting applications with high dimming requirements.
The ILD8150/E offers deep dimming performance without flicker and prevents audible noise. A PWM input signal between 250 Hz and 20 kHz controls the LED current in analog dimming output mode from 100 to 12,5 percent and from 12,5 to 0,5 percent in hybrid dimming mode, with a flicker-free modulation frequency of 3,4 kHz. The digital PWM dimming detection with high resolution and the low-power shutdown optimally match the ILD8150/E to microcontrollers. The device also has a dim-to-off function and a pull-down transistor to avoid LED glowing in dim-to-off mode.
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.
