Overview
LED2001 Datasheet 4 A monolithic step-down current source with synchronous rectification Product status link LED2001 Features • 3.
0 V to 18 V operating input voltage range • 850 kHz fixed switching frequency • 100 mV typ.
current sense voltage drop • PWM dimming • ± 7% output current accuracy • Synchronous rectification • 95 mΩ HS/ 69 mΩ LS typical RDS(on) • Peak current mode architecture • Embedded compensation network • Ceramic output capacitor compliant • Internal current limiting • Thermal shutdown Applications • High brightness LED driving • Signage • Halogen bulb replacement • General lighting Description The LED2001 is 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 4 A DC.
The embedded PWM dimming circuitry features LED brightness control.
The regulated output current is set connecting a sensing resistor to the feedback pin.
The embedded synchronous rectification and the 100 mV typical RSENSE voltage drop enhance the efficiency performance.
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 thermal overheating, overcurrent and output short-circuit.
The LED2001 is available in VFQFPN 4x4 mm 8-lead package, and HSOP8.
