Infineon Technologies Pioneers New LED Driver IC
Infineon Technologies has introduced new LED driver IC, ILD8150/E. It features an innovative hybrid dimming mode technology for achieving 0.5 percent 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 ideally suited for general and professional LED lighting applications with high dimming requirements.
The Key Features of the ILD8150/E includes:
- Input voltage ranging from 8VDC to 80VDC
- Up to 1.5A average output current
- Efficiency values of more than 95%
- Maximum duty cycle up to 99%
- Up to 2 MHz switching frequency
- Soft-start
- PWM dimming input with 250Hz to 20kHz PWM dimming frequency
- Analog dimming 100 to 12.5%
- Hybrid 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
- DSO-8 with exposed pad for higher thermal performance
The Major Applications of the device include:
- LED driver
- Tunable white
- Multichannel lighting
