The purpose of the STEVAL-ILL051V2 demonstration board is to aid in the evaluation of the LED2000, an 850 kHz fixed switching frequency monolithic step-down DC-DC converter. The LED2000 is designed to operate as a precise constant current source with an adjustable current capability up to 3 A DC.
The embedded PWM dimming circuitry features LED brightness control. The regulated output current is set by connecting a sensing resistor to the feedback pin.
The size of the overall application is minimized thanks to the high switching frequency and ceramic output capacitor compatibility.
The device is fully protected against overheating, overcurrent, and output short-circuit.
