The CXLE8292 is a continuous mode inductive step-down converter, designed
for driving single or multiple series connected LEDs efficiently from a voltage
source higher than the LED voltage. The CXLE8292 device operates from an input
supply between 6V and 40V and provides an externally adjustable output current
of up to 1A. Depending upon supply voltage and external components, this can
provide up to 30 watts of output power.The 1 includes the output switch and a
high-side output current sensing circuit, which uses an external resistor to
set the nominal average output current.Output current can be adjusted below
the set value, by applying an external control signal to the VSET pin. The
VSET pin will accept either a DC voltage or a PWM waveform.The soft-start time
can be increased using an external capacitor from the VSET pin to ground.Applying
a voltage of 0.2V or lower to the VSET pin turns the output off and switches the
device into a low current standby state.
