Infineon- ILD2111 – Digital buck controller tailor-made for LED lighting
Description:
The ILD2111 is a high-performance configurable buck controller, designed as a constant current source with hysteretic output current regulation. The IC supports output current setting at the end user with a simple resistor (Led-set like). Important parameters like current assignment and protection features can be configured by a dedicated single pin UART interface. The ILD2111 buck controller is dimmable by an external PWM signal.
Summary of Features:
- Adjustable output current via simple external resistor also at end user (Led-set like)
- Highly configurable using a comprehensive parameter set to tune operation and protection features
- Flicker-free and phase-aligned PWM dimming down to 1%
- High output current accuracy of ±5% over full output current and temperature range
Benefits:
- Quick design and easy variant handling supported by parameter configurability with .dp Vision GUI for shortened development cycles and more flexibility
- The input voltage range is fully scalable between 2.5 V and 1.6 kV thanks to low side current sensing
- Full protection incl. intelligent thermal management
Target Applications:
- LED drivers typ. from 10–80 W, e.g. 2-stage professional lighting systems
- Integrated electronic control gear for LED luminaries
