Description

The LED2000 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

3 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

LED2000 is available in VFQFPN 4 mm x 4 mm

8-lead, and standard SO8 package.
