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).
