Introduction

AI Translation

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 4×4 mm -lead package, and HSOP8.
