Description

The STEVAL-ILL051V1 evaluation board

provides a platform for evaluating the LED2000,

an 850 kHz fixed switching frequency monolithic

step-down DC-DC converter designed to operate

as 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.

Application size 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.
