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.
