Description

The LED6000 is a step-down monolithic switching

regulator designed to source up to 3 A DC current

for high power LED driving. The 250 mV typical

RSENSE voltage drop enhances the efficiency.

Digital dimming is implemented by driving the

dedicated DIM pin.

The adjustable current limitation, designed to

select the inductor RMS in accordance with the

nominal output LED current, and the adjustability

of the switching frequency allow the size of the

application to be compact. The embedded

switchover feature on the VBIAS pin maximizes

efficiency. Multiple devices can be synchronized

by sharing the SYNCH pin to prevent beating

noise in low-noise applications, and to reduce the

input current RMS value.

The device is fully protected against overheating,

overcurrent and output short-circuit.

The LED6000 is available in an HTSSOP16

exposed pad package.
