Description

■ 200 mW typical RDS_ON

The LED5000 is an 850 kHz 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

3 A 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 200 mV typical

■ Short-circuit protection

■ Compliant with ceramic output capacitors

■ Inhibit for zero current consumption

■ Thermal shutdown

Applications

terms of efficiency. The size of the overall

application is minimized thanks to the high

switching frequency and its compatibility with

ceramic output capacitors. The device is fully

protected against overheating, overcurrent and

output short-circuit. The LED5000 is available in

an HSOP8 package.
