ILD2111

概要

Digital buck controller tailor-made for LED lighting

The ILD2111 is a high-performance configurable buck controller, designed as a constant current source with average output current regulation. The IC supports output current setting at the end user with a simple resistor (Led-set like). Important parameters like target current and protection features can be configured by a dedicated single pin UART interface. The ILD2111 buck controller is dimmable by an external PWM signal.

特長

  • 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

利点

  •  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 600V thanks to low side current sensing
  • Full protection incl. intelligent thermal management

推奨アプリケーション例

  • LED drivers typ. from 10–150W, e.g. 2-stage professional lighting systems
  • Integrated electronic control gear for LED luminaries
