Description

General part information

LED5000 Series

LED5000PHR is a 3A monolithic step-down current source with dimming capability in an HSOP8 package. It is an 850KHz fixed switching frequency monolithic step-down DC-DC converter designed to operate as a precise constant current source with an adjustable current capability up to 3A DC. The embedded PWM dimming circuitry features LED brightness control. The regulated output current level is set by connecting a sensing resistor to the feedback pin. The 200mV typical RSENSE voltage drop enhances performance in terms of efficiency. The size of the overall application is minimized due to the high switching frequency and its compatibility with ceramic output capacitors. The device is fully protected against overheating, overcurrent and output short-circuit. Typical applications include high brightness LED driving, street lighting, signage, halogen bulb replacement and general lighting.
