STEVAL-ILL054V14 A HB LED driver with dimming function based onthe LED2001 in a QFN package
The purpose of the STEVAL-ILL054V1 demonstration board is aid in the evaluation of the LED2001, an 850 kHz fixed switching frequency monolithic step-down DC-DC converter. The LED2001 is designed to operate as a precise constant current source with an adjustable current capability up to 4 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.
- 3.0 V to 18 V operating input voltage range
- 850 kHz fixed switching frequency
- 100 mV typical current sense voltage drop
- PWM dimming
- ±7% output current accuracy
- Synchronous rectification
- Internal current limiting
- Thermal shutdown
