Product overview

Description

The ALED6000 is a step down monolithic switching regulator designed to source up to 3 A DC current for high power LED driving. The wide input voltage range makes the ALED6000 the ideal choice for automotive systems. The 250 mV typical RSENSE voltage drop enhances the efficiency performance. Digital dimming is implemented by driving the dedicated DIM pin.

The adjustable current limitation, designed to select the inductor RMS current accordingly with the nominal output LEDs current, and the switching frequency adjustability make the size of the application compact. Pulse-by-pulse current sensing, improved by digital frequency scaling, implements an effective constant current protection over the different application conditions. The embedded switch-over feature on the VBIAS pin maximizes the efficiency. Multiple devices can be synchronized sharing the SYNCH pin to prevent beating noise in low noise applications and the input current RMS value to be reduced.
