Description

The ILD2111 is a high-performance digital microcontroller-based DC/DC buck LED controller IC designed as a constant current source. High-precision hysteretic output current regulation is achieved by means of thedigital control loops. The driving current can be adjusted with a simple external resistor. The controller typically uses a floating buck topology operating in a Continuous Conduction Mode (CCM). In order to reduce switching losses and increase efficiency, as well as to control the switching frequency over a widevariety of external component’s values, input voltage and load variations, a frequency ripple control is introduced. Both internal and external temperature measurements are performed and accompanied by an intelligent temperature protection algorithm with two threshold values. The controller utilizes a variety of protection features, including overpower, open and short load conditions. The ILD2111 is a dimmabledevice controllable by external PWM signal. An ASSP digital microcontroller-based engine is highly configurable thanks to a comprehensive parameter set providing fine-tuning of operation and protection features. The device can be parameterized through a single pin UART interface at the REF/SC pin by usingthe .dp vision tool (see Section 5.2).

Features

  • Standalone board for evaluation of ILD2111 (dimensions: 98 x 54 x 23 mm)Primary side connected to 1st stage flyback solution with PFC (e.g. TDA4863-2G) for power classes up to50 W or dual stage PFC + LLC solution (e.g. ICL5101) for power classes above 50 W or DC voltage source
  • Hysteretic current regulation
  • Output current adjustable for up to 16 steps with a dynamic range of 1:4 between minimum andmaximum configurable by an external resistor
  • Flickerfree and phase-aligned PWM dimming based on input PWM signal
  • Fully configurable internal and external smart overtemperature protection
  • Open/short load protection
  • Overpower protection
  • ILD2111 with firmware and default parameter set
  • Device parameters optionally configurable by graphical user interface (.dp vision)
