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.
