COO (Country of Origin):

The STEVAL-ILL078V1 product evaluation board

is based on the LED6000 monolithic current

source for high power LED driving. Digital

dimming is implemented by driving the dedicated

DIM pin. Low drop-out operation with almost

100% duty cycle can be achieved. The LED6000

is a 61 V asynchronous switching regulator with

embedded power MOSFET, designed to source

up to 3 A of DC current depending on the

application conditions. The 250 mV typical RSENSE

voltage drop, the embedded switch-over feature

on the VBIAS pin and light load management

(pulse skipping) are intended to maximize power

conversion efficiency across the entire load

range.

The current limit threshold and the switching

frequency are adjustable for application

optimization. The device includes an internal 250

kHz oscillator that can be externally adjusted up

to 1.5 MHz. The size of the overall application is

minimized thanks to its high switching frequency

and compatibility with ceramic output capacitors.

Two LED6000 regulators can be synchronized in

a 180° out-of-phase configuration for reduced

total input RMS current.
